Ok, I can see them now.

1. Your lights suck to put it simply. Got out and buy a 4 pack of CFL's 23-26 watts.
2. You will only need 1 or 2 lights right now. 3 is not necessary, especially household bulbs which I assume are incandesent. Ditch em all.
3. Move lights closer with CFL's you can go 2-3 inches. It is stretching way bad.
4. You should have started in a smaller pot. 16 oz. plastic cup and gradually move to bigger pots. That one you have it in is huge.
5. Soil looks dry, what's the water schedule?

Get back to me.

Edit: This is my response from the other forum. This should really be in plant problems forum.
Lit Up Reviewed by Lit Up on . First Grow, Log one Hello everyone, I have a few questions... This plant is about 2-3 1/2 weaks old now. Should it be only this big? So far Im doing the light scheduals sort of random, Atleaste till I get a timer. But Im trying to keep it at 18/6. Though I sometimes am off give or take a couple hours. Theres a little yellowing on the bottom leaf you can see in the picture, Doesn't the bottom leafs turn yellow and fall off, Is this normal. I don't have much money for a ph testing kit and all the things. Rating: 5
