As long as you've found settings that you like and you can leave them alone, you need to focus on other areas if you have coral issues.
How old is this system?
How long have you been growing corals in it?
Are stony corals a more recent addition? (Vs. anomones, mushrooms, polyps, etc)
Can you post your most recent complete set of test results?
Instability in alkalinity and depravation of N or P can all cause problems, just to name some more popular things to consider for "blame".
A picture of one of the suffering corals compared to a pic of a one that's doing well may help too.

walked the sand with the crustaceans
I'm also running AI hydras over a mixed reef. I have less (recent) experience than you OP, but I'm finding that more blue and less white/red/green is making my corals happier, especially the acros and montis. Oddly enough, it's some of the lps corals I've had issues with, although some of this definitely been due to high flow and not inappropriate light (also elegance dying of ecs).
Here's my program. I totally made it up myself based on bits and pieces of this and that I heard from people and read online. And it's still evolving; I definitely plan to take the blue up further; not sure if the white will be staying where it is, going down further, or maybe back up a touch. Doesn't really simulate nature, isn't entirely meant too. And definitely runs too long; may shorten the duration but at present I like the early morning and evening viewing.
Someone somewhere said that the colors that really 'count' when making adjustments with this fixture are the white, blue and royal blue. The rest contribute relatively little to total PAR and you can set them pretty much where you want based on visual preference. Well that's what I read, anyway.
