SO I recently changed tank and thus changed lights. I went from 3 250 Iwasakis over a 125 to 1 400 20K xm over a 58. A few of my sps are loosing color. Mostly ones that were purple or blue are now turning a cream or light brown. EX. the LJ purple tip nana has lost the purple tips and is now all the same color. Polyps still come out on most of the sps but they all slime a lot. I started the corals at the bottom, but moved them up over about a week.
Should I be worried?

20K XM excels at most blues and purples. I would suspect they will come back once the lights are on a full schedule and they are acclimated....

1 week acclimation IMO is not long enough especially going from 250w to 400w. I personally shoot for a month minimum.
