Question

How come some of my leaves when i go to pinch the leave it just cracks and like breaks and falls and has a rough texture like its dry i water when soil gets dry

It is easier to pinch/bend leaves when the plant is kind of dry. Since they have less water content they are more flexible. If you are trying to train/supercrop, wait til the plant wants water, then train, then water. Silica can also help, but it is an immobile element so you have to add it the whole grow. It isn't as necessary with a soil grow because the soil already has some silica. Good luck!
