For sure get some more light on it, get some styrofoam sheets from home depot or lowes and build a little cage for it, get about 2 or 4 cfls on it, the grow light wont work the best unless you have more light, i tried the grow light thing last year with failure and i was a bit ticked, i would also get some more seeds,, from Nirvan or attitude seed bank. dont bet it all on 1 bush. and get a fan blowing on the plant it will help strengthen the stem.
