I have some clones that just went into flowering with powdery mildew. Actually those particular ones I am not sure whether they have begun the flower cycle as I put them all in the same room to transplant them. What can be done, perferably organically, to kill powdery mildew without killing plants which is not an option at this point? Will Serenade work? How about H2o2? Anything else?
thanks in advance!
