I actually read something recent about a guy who uses incandescent lighting to get some far red but he uses it for 1 hr at the end of the light cycle and 1hr at the beginning to simulate dusk.
I say simple is good. Folks have been growing under fluros and hps and mh for years with no added (and dangerous) UVB supplements or weird timing cycles. If it ain't broke, I'm not inclined to spend effort to fix it.

Looks nice and clean. Only suggestion I'd make is next time when you go into flower, prune more. It forces the bud growth to the top where the lights are which is especially important for CFLs as they don't have the same penetration as big ass HIDs. I LST or top and then prune away everything except for the top 3-4 nodes, then during the stretch I continue pruning until about 10-14days in 12/12.

Peace
