Gold1answered grow question a year ago What you need to do is open up the biggest buds and check INSIDE them for Botrytis. Botrytis forms from the inside out, so it is possible that your entire plant is moldy. In all my experience, I've only developed mold once inside a tent, and the humidity was well over 60%rh in late flower. Fortunately, only one bud was moldy and I was able to salvage the rest of the plant.
Hopefully that is also the case for you. Go in and check it out. If your plant is okay, find a way to decrease humidity in the tent. Maybe add a fan or two as well.
