I figured that was what the answer was going to be. I've talked to a few people in other places who have their RPs in about the same position as mine under 150W MH and they have good growth and colour (nice mix of red/green.. not all red). Weird. I'll try slowly moving the RP up with the bonsai.
The strange thing is though the RP actually started bleaching in the original spot I had it in the tank, about 6" from the surface (Yes, full story comes out). I started it where it is now and them moved it to the high 6" spot a few weeks later. Yes, I understand that more than just lighting can cause bleaching but it was given a loooong acclimation time and other frags that were added the same day were fine. I moved it to a low light area to recover and now I'm moving it back out into the bright light. It's been in a moderate to high flow/light spot for a several weeks now and colour has come back a bit but still nothing of its former glory.
So is colouration only a function of intensity and not intensity+photoperiod?
