Why acropora Tips are loosing colors

[Superlightman]

Hello,
My accropora tips are losing their colors, they become all in the same color than the body, they not look unhealthy, just loose the colorfull tips. Someone have an idea why? Parameter and icp seems all to be in range, just phosphat is a bit high with 0, 15, but that is not very bad. So what could cause this?

Pics, but could it be new growth instead of color loss?

Did you have an alk. swing?

If just the tips are pale and the coral is growing, it's quite possibly just new growth that hasn't colored up yet. Post some pics and you'll get much better answers.
