Flower pots are hard to maintain in the best case, they like more turbid water than your reef has. Bad selection choice, sorry. I killed my fair share of them years ago. Every now and then somebody reports success with them.
The torches and others may be reacting to a coral dying. Keep up the water changes and make sure your flow is good.
Phosphates need to be under .5 ppm
or even better for torches, under .05 ppm
. Many test kits have trouble accurately reading phosphates at this low level. I tend to focus on phosphates as many troubles come from them being even a bit too high. Just IMO
