I'm surprised nobody else has chimed in. I've also seen some new corals turn green under my LEDs. I think it depends on the type of SPS. I have some SPS very vibrant purple and blue while a few others have turned green. It seems like the green ones are coming around though and starting to show signs of purple and blue.

I would blame the LEDs. I had a orange plate and orange digi turn deep red, and when I dumped the LED's and went back to MH (best move ever) they went back to the orange they should be.
