Should I proceed with defoliating this plant on day 28 of flowering? I am always a bit reluctant to doing this as I think it stresses the plant a bit too much when it is supposed to be producing flowers, but I would like to hear from you guys.
defoliation implies removing many leaves at once which (as you mentioned) is stressful. At this point I wouldn't remove any leaves especially because your leaves aren't hiding any nugs underneath them. If you still want to remove leaves I would remove 2 at one time and wait for the plant recover before removing any more,that way you won't be causing too much stress. Also, prioritise the leaves that look unhealthy (which you dont seem to have at this point)
If you do any I would do selective defoliation. I personally would not touch it until it finishes bulking. It is pretty thick though. So if you had a few problem leaves covering colas I would remove is what i mean by selective. For most part I would not do anything major. She needs the leaves to produce the energy to for her colas. Looks nice 👍🏻🌱
3 weeks after beginning flower is the last time you’ll want to defoliate. After 3 weeks you will also want to remove leaves that cover buds and bud sites but other than that you should avoid defoliating any further
