earliest mold/bud rot can start?

I was wondering whats the earliest mold or bud rot can start on a flowering plant? my plants are about 1 and half weeks in flower and we just been getting rain the past week.

any idea?

I would think at the time there isnt much of as bud to hold moisture...it would be like having mold on a leaf at this point IMO

About the end of week 4 the buds can start getting thick traping moisture inside.
By the time you will notice is week 6 and its to late.
The only thing you can do is cut the bad bud out and hope air moves better around the others...
An it dosent take rain to cause mold or bud rot a good frost can, and high humidity can as well. So if gets fogging once the buds are getting close to ripe keep an eye on them...
