i have 2 plants budding that are pretty messed up. both Northern Lights they have been flowering for 4 + weeks and have been heat stressed and the buds are tiny popcorn buds everywhere. One of them still has majority white hairs but lost most of its leave. So the both are very badly dammaged but like i say 1 still has 70% white hairs but it seems like it might be a waste of time to get 1/2 oz per plant. Do you think they will make more buds or are they fucked to begin with??

It sounds like they're fucked... Light leak? If its heat point a fan at the light to get rid some of the heat.

4 weeks is still pretty young to know whats going to become of the plant, but if you want better advice then upload a pic.
