Taitoanswered grow question 6y ago Good afternoon Doudou3D,
It seems that it is indeed mold...😨 Discard these buds for smoking and take a good look at the rest that were near or alongside this one in the photo to rule them out. I don't know at what stage your flowers are (drying or storage).
In the first case, I recommend monitoring and maintaining a relative humidity of 50% for drying until they are dry and have good indirect ventilation.
If you have it stored, I recommend airing out the jar for 2 minutes once a day (make sure this jar isn't too full; no more than 75% of its capacity). And if you want to ensure good curing and storage, I recommend using humidity packs of 62% or 58% depending on whether the area you are in has a dry or humid climate; or simply to your liking 😊.
I hope my response helps you solve the problem, and I wish you no more mold on any of your flowers.
Best regards, friend
