It is folding down along the mid-rib. I know when leaves fold or taco they are trying to restrict transpiration for whatever reasons. I'm in coco/perlite 10 days into flower. Keeping them watered w runoff no dry backs. I'd call this over-watering in a peat based substrate. The runoff ppm and EC are okay. Otherwise no signs of deficiency on this particular table. Environment stable. Ideas, opinions? Maybe I am suffocating the roots and should delete an irrigation event? Thanks RUI
