I dropped the overhead light which is the twin cfl's to about 8" from plant which is about as close as I can get (will post pics of setup this week). Have been doing a lil research on some trouble with the way leaves have looked and believe I am having a slight Mag def so to see if am correct or not doing a half dose of epsom salts (read on this board that 1/4 tsp per gal of water is reg treatment) and will keep an eye on leaves for any change. Didnt want to do a full dose since I also read that too much Mag will cause other probs. Yes Cal-mag is on the shopping list but cash flow wont allow it atm
