Why are my leaves "folding?" With the fingers piling on top of each other. Really don't know.

Why are my leaves "folding?" Healthy plant. The pH swings within the proper range, no environmental stress, just weird leaf action. Temp is 76° and RH is 53%. This has to be an environmental thing? Or could Check my profile for more pics. Maybe you see something that I missed.

Hey. Your buds are full of resin. Well done. In my opinion, it must be this. Looking at your photos, I understand your perplexity. Your parameters (24°C, 53% RH) are good, the VPD is correct for this flowering stage, and the plant looks visually healthy. So, why are those leaves curling up like a "boat" (canoeing) or an "eagle's claw"? In my opinion, it’s one of these three possible scenarios: 1. "Genetic Saturation" (Most Likely) This is the downside of such resin production. The problem: When a strain is genetically pushed to produce so many trichomes on the sugar leaves, it alters their physical structure. The thousands of trichomes on the upper face exert tension on the leaf. Additionally, the layer of "frost" can slightly obstruct normal transpiration through the upper face. The result: To protect itself and try to regulate its internal humidity, the leaf curls to reduce its surface area exposure and retain moisture in the created hollow. It’s a defensive behavior related to its own excessive production. 2. "Hidden" Light Stress Even at 24°C, if your LED lights are very powerful and too close to the canopy, you might have light stress. The problem: The light intensity (PPFD) is too strong at the top. The leaf isn’t "burned" by heat, but it’s saturated with light and can’t process it all anymore. The result: The leaf curls to try to offer less angle to the light source, as if to "take cover." If the edges are slightly yellow in your original profile photos, that’s a clear sign of light stress. 3. Micro-Air Current (Ventilation) The problem: If a fan is blowing directly and constantly on a part of the plant, it dries out the air just around those leaves much more than the 53% in the tent. The result: The leaf curls to stop this forced evaporation. My Verdict and Advice: If it’s just a "strange behavior" and you don’t see any spots, rapid yellowing, or browning buds, don’t change anything. It’s the price to pay for having such a frosty strain. However, as a precaution, do this check: Check the light distance: Try raising it by 10-15 cm just to see if that resolves the curling in 48 hours. If so, it was slight light stress. Make sure the fans are oscillating and not blowing "directly" on those buds. In summary: It’s very likely a "professional deformation" of your strain. It’s too busy making resin to have flat leaves! I hope I could help you, but giving a precise diagnosis is difficult like this. Have a great day!

What's up Prilyfe13! That "folding" or "tacoing" you're seeing is almost always a sign that the plant is trying to protect itself from losing too much moisture. Even if your temps are at 76°F, which sounds fine, that 53% humidity might be a bit low for the plant's current stage, causing a high VPD (Vapor Pressure Deficit) that stresses the leaves out. It could also be that your light is just a little too intense or too close, even if it's not "hot"—sometimes the sheer light energy triggers this folding response. Check your light distance and maybe bump that humidity up to 60% if you can, just to see if they relax. Since your pH is on point and the plant looks healthy otherwise, it's definitely just a minor environmental tweak needed to keep her happy. Happy Growing, Growmie!

Leaf “folding” on an otherwise healthy plant is usually a light or watering signal rather than a serious problem. If the leaves are folding upward like a taco it is most often light intensity or heat from the lamp even if temps seem fine at canopy level. If the leaves are folding downward or feel soft it is more likely overwatering or roots staying too wet. With 76°F and 53% RH your environment is generally fine so the light is the first thing to check. Lower your light intensity slightly or raise it a few cm and watch the response over 1–2 days. Make sure you are not watering too often and let the top layer of soil dry a bit between waterings. Check airflow because stagnant air can also cause leaves to behave oddly even if temperature looks good. If the color is still healthy green and there are no spots or burns then it is not a nutrient or pH issue. Small leaf movements can also be normal “praying” behavior during strong light periods. If it gets worse or you see discoloration then reassess feeding and root health.

Hi your from the pictures they look stressed, doesn't look like any air can get through and mold will be your next problem, there's a nitrogen overload, what are your roots saying.. She needs a full service

Looks like "tacoing." Even with your temps at 76°F, the light is likely too intense or too close to the canopy, causing the leaves to fold up to protect themselves. Try backing your light off a few inches or turning the dimmer down 10% and see if they relax. High VPD can also cause this, so keep an eye on that airflow! Don't Forget to calibrate pH meter

Looks a little lush and the fact the leaves only have 3 fingers definitely points toward an imbalance in your feed. Temp and rh look fine. VPD based on leaf temp would be around 1.2 kPa, so that's fine. Any direct wind? As flower progresses, senescence can display in different ways .. the plant doesn't process things as efficiently as it once did... small problems unseen can be big enough to see, possibly. It's not always black and white. Always bit of a guess as to what is the cause of what you see. if you fertilize in a similar way next time, i'd make a note to dial back the concentration 1-2 weeks before this point or whenver the leaves started to look extra dark. or, if the natural progression of the number of lobes never gets beyond 3 and has funky shaped leaves... consider a different ratio because something isn't right.

With Dwc I'd read that ph between 5.6 and 6.4 was the ideal range. I looked through your diary and it's during the last 2 weeks where problems seem to have started but may have started sooner but only just started showing over the last 2 week. From pics it looks like the leaves have gone a dark green with a waxy look which usually indicates to much nitrogen to me. Perhaps with the PH shifts over the last few week there has become some lock out to certain Nutrients and she's been absorbing more nitrogen then the rest. My suggestion is fresh reservoir with the PH at 6.2 and see how that is, I would also soak the roots in PH 6.2 water for an hour or so before you put it back into a fresh reservoir. I'm no expert so check others advice before deciding on a course of action.

Honestly, your plant actually looks pretty solid 👍 - this kind of leaf “stacking” isn’t usually anything serious. What it reminds me of right away is light being just a bit too intense. Even if your temps and RH look dialed, the plant can still react to strong light by folding those leaf fingers in to protect itself. I’ve seen that plenty of times when the light was just a little too close or cranked up. Your environment isn’t bad at all, but at 76°F and 53% RH, you’re running slightly on the drier side for veg. That can push transpiration a bit, and the plant responds by narrowing up the leaves to hold onto moisture. If it were my setup, I’d just: Raise or dim the light a touch (nothing drastic) Maybe bump RH closer to ~60% if you can Also worth saying - some plants just grow like this. Certain phenos throw those narrow, stacked leaves and never skip a beat. Bottom line: If everything else looks healthy (color, growth rate, no spotting), I wouldn’t stress it. Just make a small tweak to light or humidity and watch how new growth comes in. You’re definitely not dealing with anything major here 👍
