Looking good. To prevent unwanted stretching keep the light as close as possible without burning her and try techniques like supercropping with some lst to keep her short and stalky. You can check out my thread here where I practiced supercropping and lst very early with pretty good results. http://forum.grasscity.com/micro-grows/1146997-400w-c-m-h-grow-follow-me.html
Very healthy looking. It does seem to be stretching, though. So... move the lights closer and probably add some more CFLs (I've got 12 in my box, some ppl go for even more!)
Also Add a fan thatll strengthen up the stalk. Make sure its blowing on your plant and your plants moving.
