They stretch during these first few weeks of 12/12. You kind of have to be prepared to change the lights daily if you want to keep them as close as possible. Personally I'd ditch the little strip light. I'm not sure how much you are actually benefiting from it. I can't tell for certain but I'd also lower your light a bit. 250Ws don't run too terribly hot so you can easily keep them comfortable. Again, just be prepared to check and adjust daily.

Hearty looking plants!
