Although I agree you cant have too many lumens, I vegged for the first 2 weeks with 3 26 watt bulbs during my CFL grow for 3 sprouts, and they grew perfectly with them at 6 inches away.

Part that worries me is you say these plants are two to three weeks old. They dont look nearly that old at all. More like one week at most. So obviously something is stunting their growth. What kind of soil is that? Is that foil in there (if so remove that). I would also move the CFLs a little further off.
