Is my coral bleaching?

[I_Got_Crabs]

I have my AI hydras in "acclimation mode" ramping up to 118% (max) from the previous settingnof 60% (max) over a two month period. Just passed the 4 wk mark. Lights are about 8" from the surface and the coral in question is about 8-10" below the surface, directly under the light. Its going through a growth spurt and the new growth looks bluish green, the old grow was brownish purple, but is now starting to turn lighter, like the new growth. I have little experience with acros, and dont even know what species this is. My main thought is that if it were bleaching, wouldnt I see similar reactions from the surrounding corals?

Ideas on what I should do next?

Not exactly sure. I dont think bleaching. To me it looks like all of your corals are reaching downward and growing horizontal, none are reaching up toward the light? The new growth on your highest green acro looks light blue and all the new growth seems to be growing downward? They all look like they have great color so far so maybe such a large increase isnt necessary? Maybe adjust for more blues and less whites if algae is an issue?
