Worried about torch corals

[Camino Reefer]

I've had these two sets of torch corals for two months now. For the first month and a half, they were both quite happy. They looked like this when I got them.

Now, one of them has retracted its tentacles and has not been as full for the past two weeks. They currently look like this.

Here are my parameters:
Salinity: 1.025
Temp: 78
Nitrate: 5
Phosphate: 0.03
Alk: 8.1 dkh
Calcium: 420
Magnesium 1350

Tank: 220 gallon display tied to another 160 gallons of added water volume from sump, refugium tank and two frag tanks. The system has been running for 7 months now.

Any advice would be greatly appreciated.

What kind of lighting are you running? I see you have them down on ur sand bed. Any idea what your par levels are?

Also have you tried feeding them???

I'm running 4 of these DSunY LED lights: Amazon product ASIN B01N0GGLHQ.

The torches are about 6 inches up from the sand bed, on a rock.

No, I don't know what my par levels are. I really should either get a par meter or rent one.

Yes, I have been feeding them Fauna Marin LPS Grow+Color pellets about once a week.

It looks hungry to me. Get some mysis and spray it directly into it. It should grab it immediately. My torches eat a ton.

Something could be bothering them, but they look hungry to me. I dose Red Sea Reef Energy A&B every two days and feed Reef Roids twice a week.
