FAQs

Does removing fan leaves increase yield?

When performed properly, trimming fan leaves can increase the yield of a cannabis plant. Trimming or defoliation helps fight pests, reduce the chances for mold, and increase light exposure and airflow to lower nodes which can increase production

Should you cut your fan leaves?

Fan leaves that are growing inward toward the plant should be removed. Bud sites that are lower down on the plant may be removed so that the plant can focus on the bud sites closer to the top. Dead or dying leaves should be pruned

Can you cut off too many fan leaves?

Although it is not recommended to remove the foliage, there can be too many in both the vegetative and flowering stage and, if there is too much foliage covering the plant, the light won’t be able to reach deep, blocking other leaves from absorbing light and also blocking the airflow that helps prevent mold and bugs

How long should I veg for best yield?

In optimal conditions, plants should be kept in their vegetative stage for approximately 60 days. This time period should give the plant the opportunity to maximise yield and acclimatise to growing conditions.

When should I start removing fan leaves during flowering?

Usually, growers trim the fan leaves weeks before harvest, which is a period that leads to senescence, a phase in the plant cycle when the larger leaves start fading away. It is safe to start removing these dying leaves and continue until harvest. However, the main trimming processes commence after harvest.

Will buds grow without fan leaves?

WHY SHOULD I REMOVE FAN LEAVES? Fan leaves are vital for cannabis plant growth and development, so removing them can seem counterintuitive. However, methodically removing leaves?a practice known as defoliation?is actually common among weed growers, as it can help to: Stimulate new growth.

Should I trim big leaves during flowering?

Yes you should ? but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.

Is 4 weeks veg enough?

Most cultivators vegetate their plants for 4?8 weeks. After this time, a switch to 12 hours of light per day is required to initiate flowering. In contrast, autoflowering plants flower on their own. Provide them with 18?24 hours of light per day throughout veg and flowering, and watch the magic happen.

Does Topping increase yield?

Does topping really increase yield. Some people claim topping does not actually increase yield, because the colas get smaller every time you top. But, it has been shown that the cumulative yield is much heavier when you top your plants. So yes, topping really increases yield.

Do bigger pots mean bigger buds?

Bigger pots does not mean bigger plants. The recommended pot size for transplanting is between 2 to 4 inches larger in diameter from the pot that the plant was planted in. This gives the roots enough space to spread and absorb more water and nutrients.

How do I make my buds sweeter?

Many sugar or carbohydrate-based supplements claim to improve the smell/taste/sweetness of buds. A cheap alternative to expensive sugar-based bloom boosting supplements is blackstrap molasses. Giving this to your plants for the last few weeks before harvest can help them get bigger and smell/taste better.

Does molasses make buds bigger?

Molasses adds sugars to the plant and will help it to bud. Like us, plants need salts, nutrients, and sugars daily. Feeding your plants molasses, what could be considered the equivalent to our eating junk food sugars, will pack on the weight to your marijuana buds.

What week of flowering Do buds smell?

Short Answer: The smell starts at 3-6 weeks old (depending on strain) even in the vegetative stage. But the smell gets much worse after plants start flowering/making buds. The leaves of a cannabis plant smell a little, but the buds smell a lot.

Single leaf fan leaves. – The #1 Marijuana Community Online

Single leaf fan leaves. Drafixo Well-Known Member Joined: Aug 22, 2019 Messages: 112 Likes Received: 52 My brother who doesn’t have the patience and attention to care for these on a regular basis asked me to look in on his plants. 2 were tall lanky and dying. But one was much smaller and even tho it looked bad it was still nicer than the other two. When I inspected it closer I realized the entire plant had single leaf fan leaves. I’ve never seen that before and thought I’d share. Reason I figure is lack of nutrition and proper care and stress but yeah a first for me! Sent from my A5_Pro using Grasscity Forum mobile app Like x 1 Joined: Sep 16, 2010 Messages: 6,113 Likes Received: 3,287 That many single blade leaves like that are usually a sign of the plant revegging or getting some light stress. A flowering plant can throw out some single blade leaves on top of the buds…but in a normal flower transition the blades of the leaves will decrease gradually…..from 7 to 5 to 3 to 1 bladed leaves etc. I would guess light stress/reveg since the single leaves have such long stems too. This is indoor right? are the tops throwing out 3’s and 5 finger leaves? that’s the important part to find out how the plant is currently doing. Like x 1 Joined: May 2, 2019 Messages: 1,647 Likes Received: 1,178 That is a revegg for sure, I’ve done this taking clones during mid to late flower just to pick phenotypes. I would suggest either letting it veg a few weeks under a 16/8 light schedule then dropping it to a 12/12. Drafixo Well-Known Member Joined: Aug 22, 2019 Messages: 112 Likes Received: 52 It is and although it’s been in a tent under a timer of 12/12 the 2 lanky tall plants were probably shading it quite a bit. Not a good set up. Sent from my A5_Pro using Grasscity Forum mobile app

Are the plants with the single and three blade fan…

Leaves. Too many grow question by WHoDat WHoDat started grow question 3 years ago Are the plants with the single and three blade fan leaves destroyed due to heat stress or should I let them grow for the remainder 5-7 weeks recommended and see if they flower properly? Never seen this before. All this happened after 9 days of being away. Philindicus answered grow question 3 years ago You got yourself a super freaky biotch. I think heat stress back your lights off that girl a breeze to cool her off. 12-12 light. I use a summer lighting schedule lights off during the day lights on at night during coolest time to deal with heat during bloom. Plants will throw 3 and single blade leaves when their not happy. Kick up the phosphorus and potassium to kick some life back into bud development.:facepunch: OutForReal answered grow question 3 years ago They will flower like if they had 7 leaves blades. I remember a clone of mine that had 3 blades leaves from the begening to the end of flowering , each times , but I kept it because the weed was awesome. You can have one blade leaves with big fat nugs MarcXL answered grow question 3 years ago Should be no big problem as you can now get things under control. My greenhouse plants looked much worse than your ladies as mine had up to 40C or 100F during heatwave and sitting under glass Removed answered grow question 3 years ago Definitely been stressed. At this point if it were my plant I would drop the lights to 10 on 14 off and see what you can salvage. That one might be chalked up to a learning lesson. Wicked_Stix answered grow question 3 years ago This could be 2 things. Either just sativa genetics. Sometimes they grow the big single leaves in flower. Or she is revegging. If you have light leaks then she is trying to reveg. If you turn their light on a lot during dark hours, even for short periods they can reveg. If you see the stem stretching out on your budsites in between the calyxes then it is revegging. Fruitgrower answered grow question 3 years ago Sativa strains can survive a fair bit of heat tbh but do Everything you can to lower the temps! The single blade leaves are not uncommon to sativa also but can be caused by stress also. Just keep growing and ease of the nutrients now. You must occasianly feed with water do wash out any excess nutes

What causes single bladed leaves? – THCFarmer

What causes single bladed leaves? OGONLY #1 I’m kind of stumped as to why several of my vegging plants have shot off single bladed leaves? Some of the leaves have a much smoother surface than they normaly would have. Yes it does seem like the plants are a bit confused as to whether its flower time or not. The ones with the smooth leaves have shot off clusters of tricomes, and have a curly leaf thing adjacent to the normal leaf upon new growth. I upped the the light cycle from 18/6 to 20/4 hoping this would correct the issue. Its been over a week and still have curly leaves popping. The single bladers have stopped though on all but 2 plants. The single blade leaves showed on 4 different strains. The smooth leaf thing is only on the SFV OG. Running 8 lamp T5 in 4 in. rockwool cubes. Plants 4-6 inches from light. Temps have been a bit low at night (lights off) 64 on average. Day time temps average 74. Anyone else experience this? BakedasBeans #2 Sounds like they re-veging man. What strains are the others? Some strains will try to flower on their own unless they are under 24/0. Some will even do eventually under that. OGONLY #3 They are actually still in veg. At least that is where I want them to be right now lol. I want them to be vegging for another 2 weeks or so. The other strains are White Rhino and Skywalker OG. Guess maybe I should go 24/7 to get em to snap out of this. fractaLz #4 I have some strains that start flowering with anything less than 24 hours… Def agree with BB, I would start start there. Doesn’t sound like you have taken cuts off of them, I’ve seen some single blades with strains after taking a bunch of cuts, but thats really rare. Def bump up to 24hrs paulycali #5 Taking a cutting when the plant is flowering will result in single bleaded leafs untill the plants are fully back into there veg stage. Its stressfull on the plant but in the end they seem to turn out just fine. Good luck man and have a happy growing of a day! Green Supreme Guest #6 Mumble mumble rootbound mumble. Peace GS OGONLY #7 Yah I forgot to mention that I took the clones in the second week of flower. No doubt that is why the plants are confused. Its strange how some are doing just fine and others (those with the curled leaves) are not bushing out. Check out the pics and let me know what you think. biggs #8 yep, defo looks like its revegging for sure. xX Kid Twist Xx Premium Member #9 yeah revegging like was stated. crom Cannobi Genetics #10 Yeah whenever you see that circular leaf shape it indicates that it has switched back to veg. You see this on plants that have flowered and were reveged to get clones. Soma is the one to discover this. Cheers, Crom ooS0uPoo #11 Revegging is the obvious answer that comes to mind (as well as the root bound GS!) ,but Ive also experienced this with an over dose of superthrive and also green fuse root stim. At the time I chalked it up to the high B vitamin content found in both and nursed the girls back to health, after cutting the steroids from their diet they bounced back. I rarely use any products with the B vitamins found in superthrive anymore so haven’t seen this in quite awhile so kinda forgot…. You wouldn’t happen to be using an additive with similar properties would you??? PoopyCoopy #12 single bladed leaves are a sign of stress. wait until it grows out and produces normal leaves before you clone it. OGONLY #13 Yes I am using Superthrive at 4 drops per gallon. Also using about 5 ml./gal B52. I…

Why only 1 blade fan leaves? Please HELP – Rollitup

Why only 1 blade fan leaves? Please HELP 🙁 #2 only seen this happen when revegging a plant. you got som splaynin to do #3 That’s the result of some kind of shock. Did the appearance of this one leaf growth coincide with your transplantation? I think they didn’t like something about the new soil. But what exactly is anyone’s guess. Growing in soil seems like growing with a blindfold on. #4 I had an issue where the incorrect program on timer was selected (only have 2 program 18/6 & 12/12), but that was at least 6 weeks ago and only effecting half of the plants. Idk how long the wrong program was on. I mean we use the timers so we can set it and forget it right? lol These are my mothers and i just don’t know what to do about it now. Also it may have been as long as 8 weeks ago, since this occured. Why would I get a month of continued normal growth before this dissfiguration? #5 That’s the result of some kind of shock. Did the appearance of this one leaf growth coincide with your transplantation? I think they didn’t like something about the new soil. But what exactly is anyone’s guess. Growing in soil seems like growing with a blindfold on. If I had to choose between shock possibilities, I would say the soil change is the closest chronological event that would coincide with the growth deformity, but what can/should I do about it? #6 You don’t know how long the wrong light schedule was running? Sorry pal, you didn’t stay on top of your grow and now you’re reaping the rewards. #7 I need suggestions on what to do about it at this point please. I know the problem is my fault and not the plants, I just lack the expertise to decide what to do about it and could use any helpful suggestions people may have. #8 If I had to choose between shock possibilities, I would say the soil change is the closest chronological event that would coincide with the growth deformity, but what can/should I do about it? When do you plan to flower? Here’s my revised theory. I think perhaps that spell of wrong light schedule is just manifesting now. This is a wild guess more than a theory, but does anyone else think a light cycle problem from six weeks ago could be taking effect now? This doesn’t necessarily mean your grow is ruined… just not picture perfect. Just keep at it. I’m sure you’re still gonna get good bud. #9 I had that same prob but early in the grow she was like a month from seed and it slowed her down all i did was bend the single blade over and tied it down and she grew 2 shoots. Happy Growing! #10 But how do I correct the problem for the new growth? Is this irreversible? Should I try trimming and seeing what happens with new growth? I just dont know what to do These bitches were supposed to be mothers #11 man you need to give some info because more than a transplant is wrong with that plant ive damaged roots and my shit didnt look like that they look very sick #12 Is there normal growth between the single blade , two little shoots , if so top the new growth or tie it. If not find a shoot on your plant that is growing normal and bend her so the normal growth is growing towards the light. Good Luck. Happy Growing! #13 Amount of blades per fan leaf represent the maturity of the plant. As the plant goes through it’s vegetative cycle, the blade-count will increase. Indica will reach around 7-9 blades per fan leaf, while a pure sativa can reach upwards of 13 blades per leaf. Hybrids will fall in the middle. As the light cycle switches to flowering, the new growth will slowly decrease the blade-count. After you…

One blade leaves in flowering cycle | 420 Magazine ®

One blade leaves in flowering cycle Hey everybody, I was wondering if someone can tell me why some plants in the budding stage start producing one blade leaves instead of the 3 or 5 blade leaves. I have a single stalk clone outside and most of the leaves near the top of the plant are only one blade. My plants in the middle of the 7th week of flowering. It is about 14-18 inches tall. I was wondering what causes this and is it normal/good. The plant looks healthy, green, and is budding fine. Thanks for the insight. No I don’t have any pics at the moment. My single blade leaves arent really part of the bud. My single blade leaves are move of the main leaves that come off the stalk. They are mostly on the very top. They are about 3 maybe 4 inches long. Actually the plant is outside. I started the clone indoors and turned the lights to 12/12 to find out if it was a male or female. After I confirmed it was a female I put it outside around 8/01. The plant was flowering when I put it outside but seemed to flower slowly. Maybe it got stressed since the light outside was still a week or so before getting close to 12/12 causing the one leaf blades. The plants/buds look good, just was weird. Thats all

Single Blade Leaf in week 5 flower

Single Blade Leaf in week 5 flower #1 All of the new growth leaves on my flowers are single blade leaves. This is with Headband and Trainwreck/OG Kush. I am running these strains at another house, and not having this issue at all. 4-5 weeks into flower. One place has a bunch of single blade leaves coming out of the buds, the other has normal 5+ blade leaves. The only difference is that the single blade leaf room has different water supply (oakland vs SF), and that the single blade room has a green light in it that sometimes is turned on to work. Its also a little hotter in the single blade room. Nutes and everything else is basically exactly the same. So why does single blade leaves occur in flower? By comparison of the two rooms, it could only be A. Something lacking in the water supply like Cal or Mg B. The heat from the light is stressing the plant (but we are talking a difference of 82-85 in single blade room and 77-82 in multi-blade room) C. The Green Light is not actually green (although sworn to be by the shop that sold it) and is causing the plant to reveg in a way. Although the buds are getting bigger day by day, so that makes me think its not that. Damnit its really annoying because the single blade leave room seems to be not advancing as quickly as the multi-blade room. #2 well idk what would be causing that if both setups are exactly the same. Did you administer the ferts yourself? are you absolutely positive that you didnt double down on the single blade room? Obviously something happened and its not the water. people grow weed all over oakland and dont have this problem. idk what happened, but it looks to be a human error based on what you are saying about the setups being exactly the same. I just dont see it being the light causing this. I dont think incandesant bulbs make the kind of light absorbed by plants so even if it is white it shouldnt matter. But I always work in the room shortly after the lights kick on, its cooler then and you get a better idea of the plants health when you see them while they are absorbing light. I mean, you wouldnt go inspect a veggie garden in the dark with a flashlight for best results would you? add the lights off droop to that and imo, its just not he best time to look over the plants. Sometimes you just gotta get sweaty, its not always easy or glamorous Damnit its really annoying because the single blade leave room seems to be not advancing as quickly as the multi-blade room. Yeah, thats to be expected. less leafs means less light being absorbed for photosynthesis which in turn means slower growth. this will aslo hurt the yields too. The plants are maturing at the same rate but the single blades wont have as much bud because it has less leafs to convert the light to energy for the plants. So I wouldnt leave the single bladers on any longer than the other crop because it will most definately chance the thc/cbd/cbn ratios and make the high different. Last edited: Jan 20, 2011 #3 I was just reading this thread regarding the effects of green light and photosynthesis. You should check it out. In summary, it could be the green lights in your room causing…

Why Some Pot Leaves Have More “Fingers” Than Others

Why Some Pot Leaves Have More “Fingers” Than Others | Grow Weed Easyby Nebula HazeWe all know the standard image of the cannabis leaf, right? By this point, you’ve probably seen it about a million times imprinted on lighters, shirts, websites, and just about everything else!Typical Cannabis Leaf ShapeNow before you examine the picture too closely, answer this: How many “fingers” or “points” is a cannabis leaf supposed to have? (more formally called “leaflets”, “segments” or ‘lobes”)Don’t feel bad if you don’t know. It’s a trick question.Cannabis leaves usually change the number of fingers/points on their leaves as they mature. The number we’re most familiar with seeing is the leaf with 7 points, but cannabis leaves can naturally grow leaves with 1-13+ points!Cannabis leaves on young plants almost always start with fewer points. The following progression shows what leaves typically look like from seedling to adult.Normal Leaf ProgressionTwo round cotyledon leaves emerge from inside the shell during germination. After that, the seedling grows two serrated leaves (“real” leaves) with one point.The first set of serrated leaves have just one pointWhen the plant grows the next set of leaves, they usually have 3 points.With this plant, you can see the first set of serrated leaves have one point, and the second set has 3 pointsThe next set of leaves typically have 5 points once they’ve grown in. I put a red dot at each point to help you see them better.The third set of serrated leaves usually has 5 pointsBy the 4th set of serrated leaves and beyond, leaves typically have 7 points each. Most plants will continue making 7-point fan leaves for the rest of their life.“Typical” 7-point Cannabis LeafHowever, most adult plants will occasionally make 9-point leaves, especially when growing fast with lots of light.This outdoor plant has a 9-point leaf in the middle of the picture (where it’s getting a lot of sun), though most leaves on the plant are 7-point.Another 9-point leafIt’s entirely ordinary for cannabis leaves to have 9, 11, or even 13+ points. It’s rarely the sign of a problem. They often appear on healthy, fast-growing plants.This leaf has 13 points!What about other numbers of “points”?Sometimes you’ll see other numbers of points. This can be the result of several factors. Some causes are benign (it’s just genetics for some plants), but sometimes weird-point leaves are a symptom of something bad happening. You no longer need to wonder. Without further ado, here’s info about other possible numbers of points you might see!1-Point LeavesIt’s normal to see single-point “sugar leaves” after your plant has started making buds. These are much smaller than regular leaves, and the base of a sugar leaf is inside the bud.1-Point “Sugar Leaves” emerging from buds are normalSugar leaves appear “tucked in” the buds during the flowering stageSometimes you’ll see 1-point leaves as the results of genetics or a mutation. You know this is the case when your otherwise healthy plant grows 1-point leaves from seed to harvest.Examples of 1-point leaves from genetics or a mutationThis is normal genetic variation. Nothing is wrong here.Here’s another cannabis plant that only grew single-point leaves from seed to harvestSometimes 1-point leaves are the sign of a problem!You should be concerned if your plant starts growing 1-point fan…

Accidental Re-Vegging | Grow Weed Easy

Accidental Re-Vegging | Grow Weed Easyby Nebula HazeWhat Causes Plants to Grow Smooth Leaves?What does it mean to accidentally “re-veg” a cannabis plant? “Re-veg” is short for “re-vegetation” and refers to what happens if a plant that has started flowering re-enters the vegetative stage. The majority of cannabis plants are photoperiod strains, which need long nights in order to make flowers/buds (indoor growers typically give 12 hours of uninterrupted darkness a day). If the plant starts getting light during its night time it responds by re-vegging.Sometimes even just a little light like a blinking LED in your grow tent is all it takes to interrupt your plant’s beauty sleep.Re-vegging happens when flowering plants get light during their 12-hour dark period. A few interrupted nights or even a small light leak can start a re-veg!Re-vegging cannabis plants show odd leaf symptoms such as:smooth leaf edgesbuds stop developinglong leaves or new stems grow out of bud sitesmain stem sprouts 1-point leaves (just one “finger” per leaf instead of the typical 7 or 9 for adult cannabis leaves)curling leaves (may look like heat stress)wrinkled, twisted, or unusual growthThis plant was put outside too early in the Spring season, which caused it to start flowering due to the short nights. As Spring progressed the nights grew shorter and it began revegging, growing these oddly smooth leaves directly out of the center stem.Unusual single-point leaves started growing out of the developing buds of this plant in the middle of the flowering stage. The grower didn’t realize that turning the light on for a few moments during the dark period could cause a problem. If the plant is getting light at night, it only takes a few days to “flip the switch” and initiate the re-vegging process!Some revegging symptoms include wrinkling, curling, or twisted leaves. These symptoms may be confused for watering, heat problems, or even broad mites, when they’re actually a sign the plant is going through major internal changes. Notice the wrinkled leaves in this picture are more smooth around the edges than typical leaves. That’s a key sign this plant is re-vegging.This plant was already flowering indoors, but when it was brought outside in the spring, the short nights caused it to start re-vegging almost immediately.These clones were recently taken from a flowering plant and have started re-vegging, causing odd growth and some smooth-edged leaves. Like many of the other cases of re-vegging, you can also see several single-point leaves among the new growth.This outdoor plant started re-vegging, resulting in odd, twisted growth as well as smooth single-point leaves with long stemsThis plant was given a 12/12 light schedule after germination and buds (white hairs) started to form. The grower realized he wanted a bigger plant so he switched to a 20/4 light schedule so the plant would re-veg. Buds stopped developing and single-point leaves started growing out of the buds. Although you can still see a few white hairs, it is almost fully back into the vegetative stage at this point.The leaves of a re-vegging plant may look different depending on the environment and particular strain. Ultimately, you know it’s the symptoms of re-vegging when the leaves appear more smooth than typical leaves. There really aren’t…
