Corals becoming pastel color?

Try feeding later at night or in the morn while its still dark , I'd also lower the intensity of your leds wont hurt anything

My corals are pretty pastel from having low nutrients in the water. undetectable nitrates and 0.02 phosphate is pretty low. Is there any algae of any kind growing in your tank? If you've got super clean looking rocks and no macro algae of any kind, or if the growth rate of your algaes has declined significantly recently, it's a good chance the issue is nutrients.
