yeah, you need more light. if you're not up to purchasing an hps setup... (I wasn't either.) drop the lights directly over the plant at about 2 inches, and use the fan as unique said. also, if your lights give off an orange or yellowish light, cop a couple daylight cfls for supplemental lighting, they won't stretch nearly as much. also, 42 watts is not nearly enough for 6 plants??? this may also be the culprit, in seedling stage i'd say that would be fine, but at this point it would be wise to at the very least invest in 4-5 extra daylight cfls.
