pavona maldivensis turning brown?

[JayChen]

I have a pavona maldivensis and it had been sitting on a medium-lower spot of my tank. I don't see any tentacles but the color is still bright. I recently moved it to a high flow high light area and gave it a whole rock to grow on. Right after I moved it there I started to see some brown spots on the coral. And it has been like that since then. Anyone knows why? Too much light? Btw I set my light to acclimation mode after I moved it so it can adjust.

I honestly can't see any difference under blues.

Well, like I described. It looks more brownish now.
