I don't recommend doing defoliation right now! It's better to wait for the first white hairs to appear at the growth points and in the leaf axils!
Defoliation should ideally be done during "stable" periods of the plant's development, which is during adult vegetative growth or flowering. When transitioning from vegetative to flowering, it's better to avoid causing extra stress to the plant! Otherwise, it might prolong the pre-flowering stage by another 5-7 days. 👆
Good luck, bro! ✊😇
