Its hard to tell without hi rez wide angle images. Bud rot sometimes looks anywhere between a wierd fuzzy blue to bluey grey to even white, Ive even seen it a tan or brown color. When you grow outdoor weed, especially up here in the great white north, bud rot is pretty common on unprotected plants. Its pretty easy to spot in person and up close. If it is bud rot, which to me it doesnt look like it, I would discard any buds that have it, and keep your remaining buds separated, not touching, until the drying process is well under way. You will know if more weed is contaminated in a week easy! Handle any rotten weed carefully so as not to spread spores and wash up real good before handling any good bud. The decision to spray or dip your dope in hydrogen peroxide mixture is totally up to you. Wouldnt hurt. But rinse after with good clean water.
