Zoa doesn't look right

[Jobu183]

Thanks in advance for anyone that can help me ID this zoa and help to determine why some heads look drastically white.

Have had this zoa in my tank for ~10 days and is my first experience owning a zoa. Any help on identification or if anyone has advice for why some of the heads are very white would be greatly appreciated.

Parameters:
Nitrates- 0
Phos- 0 (Been starting to slowly increase dosage of Reef Roids)
Calc- 380
kH- 8
Salinity- 1.025

No nutrients is bad .

I know- I've been feeding 2-3 times daily and using Reef Roids- other corals look okay, its just a couple heads on this zoa.
