Doesn't look like a lot of rock in the display, could this be happening because of a lack of nutrients/bacteria?

If they only started dying when you changed your t5 to led it is a possibility that it was the light but even usually if it's the light it takes a bit of time i.e. Bleaching, stn.

Did you check to see if predatation is a factor?

I've had some of these acros for about 5 years. I grew them out from frags and have been in this tank for almost a year. They have been happy up until recently.

I've never really had nutrients issues and I do feed lots so I don't think that's where the problem is coming from. I also was adding amino acids. I was also adding bacteria 2x per week.

I have also looked for bugs on them and I can't find anything. It's been a while since I've added any new corals.
