Advise the newbie please

Hi all, Im new to growing indoors. Right now im doing the best I can in my apartment but I dont know if it is enough or if I am unknowingly somehow killing my plants. Please tell me what you see and what I can do. Im uploading a photo below of my current environment.

I use a 400 watt Metal halide. 12-14 hours a day. besides the MH I have this flo thing 23 watts

got a fan?, mylar for the walls and use a bread bag tie to support those lanky things in the large pot

yea... the name of the game is trap the light, but keep the air movin'

Not as easy as it sounds...

Thanks Im on it.
