well first of all it looks like u should transplant into a bigger container, i use 4 cfl light for veg and two 70 watt ( trying to get one 150watt instead) hps for flowering. you should just pic up some decent potting soil with good aeration in it and if you can buy a brand that has limestone already mixed in it.

here is a pic of my flowering cab 2 Hindu Kush and 2 "so called" Critical Mass seeds ( a buddy pulled them out of some decent bud wat was sold as "crite")
