Hey there!
I've noticed a wired brownish spot a bud and I'm worried that it's bud rot. I took the spot apart and there was no visible white mold.
Is it bud rot?
That looks to be bud rot. Grab a piece of the bud and pull it will separate easily. Ifmitsmrot remove affected areas and around, get more air moving and humidity lowered. Cheers friend. Luck
