I use neem oil along with protek as an emulsifier. The protech could be substituted by a lemon scented dish detergent. I use it all the way through the vegging cycle. Neem oil destroys the reproductive cycle of the mite and therefore iradicating the colony over time. I use none during flowering.. I would not put any chemical on the buds this far in the game. You will not even want to smoke the weed. I believe in preventive medicine. You can trust in neem oil if used properly! Hope this was some help to ya!

Peace!
