Looking real good man....glad to see you got the PM under control. Its ok to blast them all over, it wont affect your buds. You can also do a plain water spray afterwards you are 100% sure there is no more PM, just keep in mind it takes up to a week to show any signs, so with that in mind, I would treat your plants for a week. After you feel you got it all taking care of, you can spray each plant with plain water and put them in front of a fan to dry them up before putting back into your grow area.
Plants are rocking man, as far as the Kandy Kush, not one of my favorites. But thats my opinion on it. Didnt have the power behind the high.
