i got 7 clones going and there about 6 week into flowering. 2 of the plant started showing Powdery mildew on the fan leaves and spreading everyday. i went to the local garden store and pick up IMMUNOX 3 in 1 it say it help stop and prevent powdery mildew . my question is do i spray the whole plant.or just spray and wipe down the infected leaves. and if i do spray the whole plant would it harm the buds to the plant?
