I definitely know about proper rh but sometimes there's not much you can do I live in a sub tropical environment and it's almost summer. So far it seems very localized. I did some surgery. 100% bud rot. Luckily the rest of her looks good for now. She smells like Skittles. I have so much bud here I could lose the whole plant and I'd be fine. This is why we grow multiple plants. And clones.

Edit: ironically the humidity is so high BECAUSE I have so much wet soil and foliage in here (less plants next grow, 3+clones in possibly 5gallon pots).
