Well since it sounds like you haven't seen any dead mites I'd be more inclined to say mold... and white/fuzzy is usually a good sign of mold!!

WOW is right! Great eye man... so many others have already scrutinized and smoked these nugs without any second thought apparently! I probably would've missed that, but now that you point it out I think it's something to be concerned about...

Cannot believe that it placed so well in a competition with mold! Goes to show how meaningless these competitions really are!
