middie, it sounds like you have a fairly ideal situation for bud rot - warm and wet (high humidity). The best things you can do are lower humidity and increase air circulation. Since the plant is outdoors, you can't lower humidity, but you can increase air circulation by pruning back fan leaves.

Just keep a close eye on the plant for a browning/rotting area - prune any such area. And, you may want to harvest the entire bud on which the rot has begun. I would probably go ahead and remove any such infected area prior to drying and curing.

Also, there is a product called Serenade. It is an organic fungicide from what little I know about it - I've never used it, but only heard about it. It is supposed to destroy the bud rot bacteria, without causing harm to the plant.

I hope I provided some help.
