I see now. So it's like the light for the room that you are able to sit the plant under and I'm assuming you can't add on more light because it would be weird having like 8 CFL's hanging down as your (living room?) light? :jointsmile: Makes sense lol

I would guess that the yellowing is mostly due to no food supply for the maturing plant... and insufficient lighting. Just the nature of the beast. Even with adequate CFL lighting... they simply can not penetrate deep enough to supply the lower leaves with usable lumens. You seem to have some space between nodes... since this is kind of a "whatever's whatever" grow, try your hand at Low Stress Training. It will even out the canopy level and allow the majority of the plant to receive light... instead of just the top. It will also let you veg the shit out of it to get it to sexual maturity. What do you plan for the 12/12 light schedule? Hopefully not just shoving it in a box somewhere. You'll need total dark, but continuous air exchange.
But yeah... to (try to) answer your question:
You will need a food source to encourage more intense growth. You would need more light to somewhat eliminate lower leaf yellowing. You should also seriously consider training the plant... and planning for the flowering phase. If you just want to stick with what you have going... I wouldn't worry about anything at all unless the plant turns into a withering toothpick. I understand what you mean about setting up official equipment when you are just going to pack up and move. Although, even when it IS totally set up... it's really just starting. Anyway...
Shit's green... be thankfull! :jointsmile:
