we call the light fixtures " hoods".

What is the the area for a 6" 1000 watt hood? I'm gonna break it down. Please excuse the newb talk.
I have 13 plants flowering. I have 10 under t5 lights and 3 under a 600 HPS. I also have a 1000 watt switchable ballast i can hook up.
Should I put them all under the 1000 watt? or keep them the way they are? The reason I ask is the ones under the T5's are doing just fine. I do have pics ,but I don't know how to post them.

The NEWB Flowering count
1- Alaskan thunder fuck
1- sweet tooth
6- Purple Odyssey
5- Purple Train Wreck I do have 2 more Sweet Tooth clones but I segregated them because they look retarded or deformed for some reason.
