Birdsnest growth or bleaching?

[Hurricane Aquatics]

Hey all,

Had this frag now for about 3 months. It's been doing great the entire time and growing well. Light change about a month ago, but it is in the exact same par range (have my own Apogee 510) and grew quite a bit in that month under the ATI Straton.

Polyps are still out even on the white end pieces. Have always had the white tips of course, that's normal growth, but they seem to be getting longer.

Know a good amount about SPS, but this just makes me a bit paranoid.

Parameters that matter:

1.026
9.0 KH
1480 Mag
470 Cal
78.5 temp

Phosphates and Nitrates are undetectable, but I do have some Cyano going on in places, so they are there.

Let me know what you think, bad pics, but best I can get.

If that is not bleaching and that is it normal growing, that frag would drove me crazy LoL

Arrows look normal, Circles area look like bleaching to me.

Looks like growth to me.

But keep an eye on it just to be safe, only the tips should be white, if it starts to progress dim your lights or lower it.

Thanks all,

I have dimmed my whites a bit and we'll see how that goes.
