wow.. yeah.
first things first "homie". You have to be patient.. patients is key. Growing.. is more than just throwing a seed into the ground and letting the plant grow. Its a true form of art IMO. You have to treat your plants with as much love as you would give to your own child.
I'll help ya out some.. The reason for your plant being droopy looking.. could be a multitude of things. My guess would be that she's getting too hot.. or you have her set to closely to the lights (bulbs) that your using. Either that, or your over-watering her.. A little tip for knowing when to water your plant(s) is to wait until the top layer (top 1/4th inch or so) is crispy and dried out.. thats when you should water again.
Good luck man.. and remember, be patient.. and just chill. Also, read up on growing cannabis!! I can't express how important it really is to read all you can.. every piece of information you can get your hands on.. read it.
peace.
