Thanks man... The sulfur burner we've been using seems to be working great. We brought new plants into the grow room the other day and put them on the same system as the infected ones and they havent caught it. Still growing strong. So the sulfur burner seems to be doing the trick.

We also bought Safer 3-in-1 spray, which also has sulfur in it and things look to be going in a much more positive direction.
