Well if it's over watering, mine will never get well. They're in hydro., but had the exact same symptoms. Drooping leaves and minute brown spots on the face of the leaves. I don't think it's over watering cause I flushed mine and remixed the nutes to a lighter dose and the new growth does not exhibit these symptoms any longer. I think I was overdosing them with happy juice. Fox Farm stuff. Anyway there growing fine again.
