My First Grow

Hey all,
New to the site, but have been browsing it for a while. Anyways, i picked up 8 clones from a buddy, not sure what strain, but i decided to experiment and see what happens

My Setup:
-in at closet in my apt, covered in tinfoil for reflection
-4" diameter pots
-24" flourescent light
-right now they are running 18/6
-fan running 24/7, oscillating
-miracle grow potting soil

i have had them a week today, and there has been noticable growth (ill post some pics tonight, my cam is busted so ill have to borrow one). they're a little droopy but i believe thats from overwatering? i read this in the marijuana emergency room forum here haha...any advice or comments is MORE THAN WELCOME, hopefully ill have pics posted soon...if anymore info is needed, ill gladly post it
thanks!

what kind of MG are you using? if you use organic that is better, the other stuff has time released nutrients and will grow well for awhile and then the nutes will burn it to the ground.

its the time released nutrients MG i believe...i take it that its not good to use? ive read alot about growing, but i could use any advice possible...ill be taking pictures tonight
