Can someone tell me what the blotchy vein pattern is? Is it normal? I have seen it on corals prior to STN, usually due to not light acclimating. Should I take this as a sign of something? This is a tabling tricolor valida.

Where it came from:
The coral is new. It came from a frag tank, it was 10'' deep in the water. The frag tank was lit with 8 bulb 4' T5 that is fully lit for 5 hours and half lit for 10 hour.

My tank:
The thing is sitting directly under my 150W 14k lamp 8'' from water and 14'' from the HQI bulb (new bulb). I thought light acclimation was unnecessary considering where it came from. The polyps on the outer ring and the purple growth tips are extended, while the polyps on the inner branches is not extending. I light the tank with 54W of LED for 10 hours and HQI kicks in for 4-5 hours during that period.

My water is perfect.
Thanks
