Before you start feeding the coral make sure all your parameters are within range

Mag
Calcium
Alk

Low Phos ** this is one of the number 1 inhibitors of sps growth as if effects coral ability to uptake and use nutrients

Nitrate within low range *** but not 0ppm

These first and you should have decent looking and not sad corals. Also i think running some carbon to clear the yellowness out of the water and give your corals all the Par your lights are getting

Then after that I would start by doing a few more water changes say every 2 weeks for the next month to catch up on some trace elements and give the tank a new lease on life

THEN if after that you notice still sad corals go for some Amino acids or 2 part trace elements ( i don't have a good recommendation but i have used Reef roids for the coral food and Fuel for AA but only once a month and sometimes not even that

my 2 cents
