Hi Gray,

Slow growth could point to phosphates and tip burn could be down to alk so i would double check them on different test kits.Also check the obviouse things like salinity and temperature as these are often overlooked.Did you add a large ammount of phosphate remover in one hit as this can also stress corals?

Also check the dates on all of your test kits as some can go way off with age.The salifert alk test being a classic one.

I know you said the bulb s are only a couple of months old but check the glass shield.
I found to my cost last year that one bulb had cracked and I never relised until I had major bleaching. The shield had cracked and was suspended under the shade.

Just a thought
