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.

salut .t'es tête sont pleines de résine. bien joué. à mon avis soit doit être ceci. en regardant tes photos, je comprends ta perplexité. Tes paramètres (24°C, 53% RH) sont bons, le VPD est correct pour ce stade de floraison, et la plante a l'air en pleine santé visuelle. ​Alors, pourquoi ces feuilles se replient-elles en forme de "bateau" (canoeing) ou de "serre d'aigle" ? ​À mon avis, c'est l'un de ces trois scénarios possible : ​1. La "Génétique Saturation" (Le plus probable) ​C'est le revers de la médaille pour une telle production de résine. ​Le problème : Quand une variété est génétiquement poussée pour produire autant de trichomes sur les feuillesnourricières (sugar leaves), cela modifie leur structure physique. Les milliers de trichomes sur la face supérieure exercent une tension sur la feuille. De plus, la couche de "givre" peut obstruer légèrement la transpiration normale à travers la face supérieure. ​Le résultat : Pour se protéger et tenter de réguler son humidité interne, la feuille se replie pour réduire sa surface d'exposition et retenir l'humidité dans le creux créé. C'est un comportement défensif lié à sa propre production démesurée. ​2. Le Stress Lumineux "Caché" ​Même à 24°C, si tes lampes LED sont très performantes et trop proches de la canopée, tu peux avoir un stress lumineux. ​Le problème : L'intensité lumineuse (PPFD) est trop forte au sommet. La feuille n'est pas "brûlée" par la chaleur, mais elle est saturée de lumière et ne peut plus tout traiter. ​Le résultat : La feuille se replie pour tenter d'offrir moins d'angle à la source lumineuse, comme pour se mettre "à l'abri". Si les bords sont légèrement jaunes sur les photos originales de ton profil, c'est un signe clair de stress lumineux. ​3. Le Micro-Courant d'Air (Ventilation) ​Le problème : Si un ventilateur brasseur souffle directement et en permanence sur une zone de la plante, cela dessèche l'air juste autour de ces feuilles-là, beaucoup plus que les 53% de la tente. ​Le résultat : La feuille se replie pour stopper cette évaporation forcée. ​Mon Verdict et Conseil : ​Si ce n'est qu'un "comportement étrange" et que tu ne vois pas de taches, de jaunissement rapide ou de têtes qui brunissent, ne change rien. C'est le prix à payer pour avoir une variété aussi givrée. ​Cependant, par précaution, fais cette vérification : ​Vérifie la distance de la lampe : Essaie de la remonter de 10-15 cm juste pour voir si cela résout le pliage en 48h. Si oui, c'était un léger stress lumineux. ​Assure-toi que les ventilateurs oscillent et ne soufflent pas en "tir direct" sur ces têtes. ​En résumé : C'est très probablement une "déformation professionnelle" de ta variété. Elle est trop occupée à fabriquer de la résine pour avoir des feuilles plates ! j'espère que j'ai pu t'aider mais dire un diagnostic précis est difficile comme cela. je te souhaite une bonne journée

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.

Can only be 2 things, light or heat stress.

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 👍
