Hey all... I'm wondering about the usage of Serenade, specifically in outdoor growing. When do I start applying, and when do I stop? The guy at the local grow shop (whom we've named "Yoda") said, simply, "cottonballs". In other words, when the buds look like cottonballs (we don't quite talk about our little friends openly). How has everyone else used this? Or, I suppose as far as the timing goes, any other fungicide? Thanks in advance all!
