hey Marsad, personally i never suggest to defoliate during flower, because why? well, like you ask "How long will she be stressed?" but you are in flowering stretch, so you know are disrupting the flowering. Logically if you disrupt flowering , there will be consequences on the final product like less yield from disrupting the stretch, less potency or less fattening. So there's really no good reason to do it as far as i can see, for sure there's no evidence it encourages growth so it's up to you but I wouldnt do it. Anyway the good news is that she will not be that much stressed maybe 1-3 days max anyway. hope this helps ! 🚀
