I have been growing my girls under a 600W dual spectrum HPS lamp. They are growing only very slowly and the edges of the leaves went yellow then brown and look like they are dying. The lamp is about 3-4 feet from the plants. I have seen pictures of the nutrient deficiency porblems and it doesn't really look like this. Is it likely to be too hot? I also got the impression that the would grow fairly quickly. They are currently only about 3 inches tall with about 6 leaves. Please help.
