You can salvage some, but be picky. They will mold big time. I cracked open a moldy bud yesterday in the sunlight & saw a cloud of spores burst from within.... YUK!
Keep those buds that you salvage separate for a few weeks just in case you missed some. The 1 i found yesterday was fine on the top 2 inches of the bud. about 4 inches of crap, then the rest was good.
It's all part of natures cycles & we can't screw with mother nature. She makes killer buds!
