What is going on with my torch?

[NVCyberPro]

I have several corals in a 76 day qt program before going to my dt. All were doing well, most are growing like crazy but starting 2-3 weeks ago my torch is dwindling. I tried adjusting water flow with no success. PH 8.2 1.025 78 deg 420 ca 0 ammonia 0 nitrite near zero nitrate. Current USA lumen pro, 29 gallon bio cube. All help would be appreciated.

Could be too little light. 0 nitrate will also cause problems since the coral needs nitrogen

Also what is the alk at?

I don't have an Alk test kit, I'll get one and check. Thanks

That is the no.1 thing to test with stony corals. It drains faster than any other element you will be dosing.
