Well, seeing as we have TONS of info to go off of, your doing amazing. On a more factual standpoint, for that thing to be a few weeks old, is horrible. The soil does look high quality, but far too damp. Also, when using soil, have about a 30-70 ratio of perlite to soil. Personally, I like more of a 50-50. For lighting, I'd say that's why the thing is so small, you need about 5,000 lumens per sq.ft. I'd recommend using CFL's and around 6 of them, 23w. 5500-6500k for veg, 2400 for flowering. You need good ventilation, and a fan blowing on the little one to fatten up that stem. Also, read these forums.
