Well you would have to have you actinics and fiji purples on the outer 2 sections... plug the cord that powers those bulbs into a timer, then plug the cord for the 10K's (that would be in the inside 4) into another timer. Set your timers accordingly.

It's not CRUCIAL where you put what bulbs as they will all spill over each other anyways. Just don't install 10Ks on your outsides if you want to have actinic lighting come on first and go off last.
