plant that b*tch in some soil!! :P your plant needs nitrogen while it's growing. very important. in fact, lack of nitrogen and too much potassium can lean a plant to turn male (no clue how that works with feminized seeds - hermie?).
in nature things grow without our help all the time. imho, it's much easier to kill a plant from doing too much rather than sticking it in some potting soil, giving it light and water, and letting it do it's thing. give it balance and it will love you (it's not called 'weed' because it needs super perfect care).
