Should of kept those floro's closer earlier on. Looks like they are stretching and that's it. When In a small room its easier to bring the plants up higher than to lower the light. With that cfl you should be able to keep it within inches of the top for optimal lighting.

So you don't use the 600 watt???Consider buying an air cooled hood to get your temps lower.That should reduce stretch also remember some strains also stretch a lot the first weeks of flowering,but with that said nothing beats hid,those cfls cant compare.

It looks like u fixed the problem. U have 6-10 inches between your nodes on the middle of the plant and at the top the nodes are packing in a lot tighter, so I think u will be fine.
If u want I can help u get ur temp prob figured out so u can use the HPS and have cooler temps.
How many cfm's are u using to vent the light?
What is ur room size?
What is ur exhaust fan cfm?
What is the intake air temp?
