That's what i thought it was bud rot. Na bro, Don't smoke that shit man, I don't think it's a good mold like penicillin and i dunno if penicillin would be good to smoke lol.  Get that humidity down next round, I cheaped out before and left the dehumidifier off, and got bud rot in my most nicest/biggest buds, that shit ain't happening again, I set my dehumidify on 45 and it keeps my flower room at 50% which seems to work out fine.  Happy growing.
