Others are doing this too. Not sure if its in strain or less than optimum environment? Flipped Oct. 20 growth has been great in flower.
Light has no dimmer so was too intense during veg. Raised fixture and dropped 2 hours of light, helped alot.
Am aware that heat and light stress cause leaves to curl or fold up but never had this happen in flower. Maybe shes a keeper and lm reading her wrong.
Am using borrower light and is 60w stronger than led lm used to. All other leaves look normal. No yellowing to speak of anywhere! Affected buds are 1ft from light so shouldnt be too intense.
Any ideas? Not doing anything until l know %100. Seems to start at tops of plant.20211121_010741.jpg
