a little help please

[Jeanna]

New here, and I could use a little help diagnosing my problem. Two of my girls have started turning yellow on their new growth one of the girls the yellowing might be taking over the plant I am worried that they are either to cold or lacking some nutrients? They are in the garage in a grow tent with a 400 MH and i have had them on water only for the last week due to some yellow tippage i thought may have been from over fertilizing. They are currently vegging. Should I get a 1,000 watt or do i have a nitrogen problem? Any help would be greatly appreciated. I have included pictures of my girls with the problem.
