Not Sure Whats Wrong First Grow

Hey guys this is my first grow, just having a few problems with my one plant. So these plants are two weeks old bag seed, and i have them under 6 26watt cfls. I water them about every two or three days, and havnt given them any nutes yet. Oh yea i started lsting them so thats why they are like laying down. The first couple of pics is the sick plant, just has those brown spots on the lower leafs, and just dosnt look right. The last pic is of the healthy plant, well at least it looks healthy to me? Any help would be appreciated. Im thinking of transplanting in a week or so, let me know how im doin.:smokin:

They are starving. It also looks like you got a heavy peat based medium, check your run off, I think it could be to low.

Several probs.
Peat- yes that looks peaty to me... get that thing repotted in real soil NOW... shake as much of the old stuff off the roots as you can without damaging them.
Depth in pot- level of soil should be less than an inch from the rim of the pot to avoid air stagnation around the stem and among the low branches
Moisture- Awful dry there
Calcium deficiency- YIKES that weird crinkly appearance going to necrotic blotches is a good sign... time to hit the thing with CalMAg Plus. But remember that the soil pH (probably in the low 5s because of that shitty peat dirt you are using) is locking out the nutrients your plant needs, so whatever feeding you do is going to be kinda pointless until you get your pH situation sorted out.
