SPS have stopped growing

Hi guys,

So recently within the last month or so I have noticed almost all of my SPS and similar corals have stopped growing. For instance my green slimer would have white tips from the growth and now the green has progressed all the way to the tips and show no indication of new growth. My LPS, Zoas, inverts seem to be growing same as they ever were as well. None of the SPS have lost any color but it seems like the tips just don't have any vertical growth and they are not encrusting either. I Have a 100g cube with a radion XR30W pro. The light is 18" above the water and my SPS are approximately 5-6" below that. Radion is running at 85%. Also I have an MP40 running around 60%. My dKH is at 9.4, Calcium is at 440, Mag is at 1340, phosphates at 0.00. Also I am running GFO and carbon, along with my skimmer. Any ideas would be greatly appreciated. Is it possible I am running the light at to high intensity?

Thanks
