If you sprayed neem, baking soda, or insecticide on the plant that’s your problem. If not it’s probably a root problem since the buds are too small for rot (unless you spray your buds or have super high humidity, in which case it could be rot). Think I nailed it!
So I think I've got some baking soda / water / cleaning solution trying to clean off some white powdery mold, and I got some bud worms causing bud rot on other plants..
I caught the bud worms super early, and have treated for them within 24 hours of finding them.. re applying all my anti pest stuff tonight/mold
So the burn is from when I was treating for some WPM and I might not have cleaned out my container good enough and it might have had something really harsh
