Yeah I dont defoliate much during flower because I believe nutrients are stored in the leaf which get used during flower, but I just improved light penetration a little.
I remove them when they go yellow and soft.
These strains, I gave seeds to someone, he mixed them up when germinating them, I took 2 cuts each off 2 plants, 3 of the 4 survived, so I've got 2 of one type, one of another. Im almost sure they are Sunset Sherbet by Phenofinder, and Notorious OG by same, but doesn't matter, will all end up in my lungs!
