I have 6 plants that came from a dispensary in clone form. In the store they seemed fine. They started growing tiny patches of white powdery mildew on the leaves a day or two after i took them home. I quickly removed every leaf which has the mildew. Basically its gone the day it shows up. I had them in a closet for about 2 weeks with the lights on 24 hrs a day so it was about 88 degrees for a those 2 weeks, and the PM was gone for those 2 weeks. Now i moved them out of the closet, they are bigger and i cant keep the heat that high in this new room. The PM has came back on a few leaves and i cut them off. If i keep cutting the leaves while the PM is still just a tiny spec will it go away? I know its systemic but maybe 5% of the leaves tops might get one single spot of it. It always comes in 1 tiny spot on the leaf like it only had 1 spore. Any ideas? They need to go into flowering soon.
Spray em with an organic fungicide like a copper or cinnamite product. It should take care of it for you. In addition making sure you have good air circulation will help. A fan. Good luck!
really copper how many people can vouch for this? and what kind of copper would i use exactly and how much?
