Ok. You said somewhere earlier you had 4' fluorescent fixture ( assuming 2 tube shop light)? I would put that back as over head light & use the cfls as side light. You can even go a couple wks into flowering with that before you add the 250hps. Their color is good. I'm assuming you don't have other lighting in place, just what is shown in pics? Correct me if I'm wrong. If you have lights not in the pic, that would void the first three sentences in this post. Crap! Unexpected company. Be back in a couple hours.

PEACE!
