what are fan leaves usefull for?, when the plant is in veg then they gateher light and photosynthesise but when its in flower they jus get in the way, blocking light from the new flowering shoots below, not that it makes a lot of difference either way.

i overwaterd my plants, they curled under, dark green in colour.
I then dramatically cut back on the watering and the lower leaves turned brown and dry, which makes sense for underwatering in my case. I took em off v esily and waterd more, its recovering well now.

PH sounds logical
