What are symptoms of fertilizer salt damage?
I have an earlier post on older plants with new growth leaves that are smaller. Some get a brown, or burnt looking edge. Most are more yellow than normal. I think that it has been because of fertilizer salt build up in the soil. I flushed the pots with fresh water for the first time since last Summer (I grow them under HO grow lights during the winter). I think they are doing better already. Has anyone else had any experience with recognizing fertilizer salt build up in potted plants?
