First I would like to thank all the members who do so much work for these boards. I have spent the last month just browsing through journals and FAQs and I have learned a lot.

However, there are some problems with these plants that I am not sure how to diagnose. I think they have nute burn or a mg deficiency or something. The plants are wilting, have leaves curling downward, rust colored spots along the leaves, and generally look sickly.

There are 3 plants in rock wool burried in potting soil. The plants stretched severely because for the first 3 weeks they were grown with light from one florescent tube. Light is now from a 600 HPS. They are 5 weeks old. I flushed them with about 2 gallons of water over about 2 days ago.
