Yup go to a good nursery or hydro shop and ask for Serenade. It smells like a bag of assholes in the sun, but works...take it outside..spray liberally, and the mildew will disapear for a while. So keep it handy.12 bucks but it works. Remove any and all leaves with even a hint ...then spray. A little prune doesnt hurt to help air flow in humid grow rooms. Boost potasium in your soil or res to help your plant stay strong against mildew and fungus.
