Birds' Nest bleached/browned out.. help?

[DracoKat]

I have/had this beautiful big colony of birds nest. Yesterday was fine, today it's all bleached/browned out. Mostly brown with a few patches of white.

I am in process of doing testing, but anything I should look for while testing?
What can I do to bring it back? it was one of my favorite piece in the tank

Everything else in the tank is doing well, other SPS's are doing well.

Lighting has not changed- changed the bulbs 2 months ago (4 T5 bulbs).
The only thing I was dosing is 4 part Korallen coral system (Wednesday was the 5th dose, been dosing once a week), and BRS 2 part.

Will report back soon as I finish testing. Photo to come in a moment

I would Frag the parts with coral to keep that part living

here's the test results. I left my ammonia and Nitrate kits at work, so I can't test those.

Nitrite- 0
Phosphate- 0
Calcium- 430
Alk- 9 dkH
Mag- 1280
PH- 7.8

edit- will frag the ends.

it's almost all white now.

nothing can be done to save it? Think I don't have enough nutrients in my tank? I may have to dose something to bring it up.. any ideas what?

More fish food? Your other corals also look to have duller colors than they did before.

@BoomCorals the first photo was edited to show the colors. the second photo I did not edit. I wouldn't go by the colors (I should've clarified that).
Colors are same on all corals

I would go ahead and frag what you can before you lose all of it. Then at least you have some left if you can't save it. I had this happen with mine. It sucked but the frag is doing great now.
