Inspect everything and chop anything with mold immediately. Just toss it, it's a loss. Once you've chopped all the moldy buds off (and don't be stingy, get rid of that sh*t) then harvest your plants. I'd take off all the fan leaves and keep the buds in direct breeze while you're drying them to keep any mold spores from growing. I'd dry faster than usual if there was mold. Most of the buds should be okay... you're def close enough to harvest now anyway to go ahead and chop IMHO
