I bought this salvia divinorum, it was doing fine but suddenly new leaves began to curl, just the new leaves, and stop growing. I've detected very small amount of mites, so i sprayed sulphur (white on levaes) to control it. Seems to removed the mites, but i don't know if that the real problem. the new leaves and shouts stop growing and are very dififult to develop. I'm afraid of losing my plant.
