1st INDOOR GROW. ADVICE PLEASE!!!!

this is my 1st grow ever. I'm using 4 60 watt daylight cfl's inside a box for a subwoofer. I put a layer of tinfoil all over the inside and one sprouting plant, the other 2 i just put in.
I water it about once a day, or when the soil is pretty dry. I used a miracle grow moisture control/ nutrient soil. Do i need extra nutes when the soil is depleted of its nutrients? if so when?
comments? suggestions? questions? anything will help thanks

lol sorry for the big pics
noob here
dunno how to fix it
BUT WHAT DO YOU THINK ABOUT THE GROW BOX?!

anyone out there?

in that cabinet u can grow 1 plant till the harvest period.
2 plant can also be possible. but 3 plants are beyond the limit for there.
but i think in your cabinette you can grow them for a while during 1 month.. till they grow up a little
you also want to make that cabinet a little higher. increase the height...
i think you are using aluminium foil to reflect...
but you want mylar. best choise

note: each plant needs 1 cfl bulb ( more than 23 w, ideally 45 w )
cool white (6400 k) till flowering (during vegatation)
warm white (2700 k) till harvest (during flowering)
