Green Star polyp and lobo retracting

[SteveEreef]

So I’ve had the GSP and lobo for over a year. This evening both have retracted. The other softies, Lps, and sps are fine. My parameters seem fine sal 1.025, alk 8.0, ca 420, mg a little high 1560,
Ph 8. 3, my NO3 and PO4 have been low and I have been trying to raise up a bit, approximately 0 and under.03. Any ideas as what could cause this?
Thanks

Not sure , but I wouldn’t change the whole tank for two corals and I’d wait a few days.

Thanks. Will see how they look in a few days. I have to remember patience is key.
