that's what I thought, with enough air movement it won't happen, but about 1 month ish ago I had to deal with bud rot for the first time. Only advice for you is if you have some massive buds and they have massive leaves, dont try to remove the fan leaves by pulling them, cut them with scissor away from the bud instead. I try to remove a few fan leaves that were shading lower growth and I actually hurt the plant inside the bud and I am guessing it started bleeding, it got moist inside the bud and started rotting . I have since added a dehum and more air flow but I gotta say I thought there was no way I would get mold and I did. high 50's is risky business.
Both plants I ever had to deal with rot, it was in the main cola about a week after I had pulled the fan leaves off (on purpose to remove them), it could have been coincidence but the rot started exactly where those fan leaves were.
Also, when the buds are big, every day give a gentle pull on the fan leaves to make sure they are tight in there, if the leaves comes off easily and you didnt mean to take it off the plant, that's trouble, you MUST take the plant outside of the grow room to inspect it, if you inspect in the grow room especially with the fans on, you will spread the spores all over your healthy plants, you dont want that
Anyway I dont mean to scare you but just to be on the safe side.
