Ive been having some troubles with my 3 week old plant. It is only 3-4 inches tall, with only about 8 tiny leaves (about the size of a fingernail). I know it hasnt grown well partly because of the shitty 120W incandescent flood lights I was using, but I am starting to get concerned that it may be the type of soil they are in as well.

I read in another thread that soil that has bark in it is very bad, it gets in the way of root growth and tends to be slightly too acidic. Is there truth to this? And if so should I consider completely changing my soil? I have ordered a 400W HPS which should be here in a few days, I think that will help the plant enormously, so should I wait and see how it responds to that before getting a different soil? What is a good (but affordable) type of soil for my plant?

Fertilizers. The tips of some of the leaves are turning yellow/brown. Again I think this is partly because of the heat from the 120W incandescents but I'm starting to wonder whether it is a result of lack of nutrients. Its been 3 weeks so I am guessing the nutrients in the original soil are almost exhausted, and the yellow leaves are a sign of nutrient deficiency. What is a good (but affordable) brand of fert? What is the best ratio to get?

Thanks again for any help!!!
