Coral concerns

[Mr_Banana_Pants]

I have a few coral questions. I went on a 5 day vacation and the care taker of my tank accidentally shut off the timer for my lights. My hammer has 2 heads, one is fine and the other looks awful with a green mossy looking stuff, should I cut off the bad head?

The other two are corals I bought on WWC cyber Monday live sale. They were in a frag rack towards the top of my tank and seemed fine initially, but now look bleached out. Will they come back?

This was the frag rack before my vacation

Thanks to everyone in advance

I'd move everyone to the sandbed. (Or move the frag rack down to sand level). Then every week I would move them 6" or so upwards.). I'm guessing the light stayed on the whole time and never went off. What are your NO3 and PO4?

My nitrates are about 50, doing a water change Saturday, don't have a test kit for phosphate

Get it all back to regular schedule.
Your No3 might help you a little let to be as of now.
Test for your ALK to see where that is.
