What Kelvin rating are those 400w Halides? I don't see much light in the corners from that light. And at 400w, they are more than sufficient for your needs. Your phosphates should be kept under .03 and your Nitrates should be kept under 10, that may be your issue. dKH is a tad low at 7, should be between 8-12.
