And no Petco is not a LFS lol. Please don’t come back tomorrow and say you had petco test the water. Go to a real LFSYes, and besides that, you need to learn to interpret correctly the readings from an ICP... Your ICP value for nitrate is close to 37ppm, not 0,2 as you stated on your first post. its hard to make any adjustments if you don't really know what reading you are getting...
As @VintageReefer said, Get your water tested today and lets work from there.
Well calibrate it and recheck your salinity.No i haven't calibrated the refractometer …my source water i wale water but passes trough 7 stage reverse osmosis …. Yes filters replace regularly every week…

I mean it’s good you’re replacing your filters but THAT often? Why? Is your main supply fouling your filters THAT quickly? Every week is excessive unless you’re generating hundreds of gallons weekly and you can’t keep your TDS down. Doesn’t seem right.

At this point I don’t know what’s right or wrong as for your values. Icp is only as asccurate as the date of the sample. And your results are not close to the icp results
Your test kits reagents could be expired, fouled (water got in them) who knows.
Can you take a water sample to a LFS to get a third opinion and have them check salinity, nitrate, alkalinity, calcium, phosphate, magnesium
If your corals were doing okay 2 months ago with high nitrates, and now are doing poorly with low nitrates... I think you have your answer. You're starving your corals of Nitrates.0.2 was with hanna yesterday… that icp testing was done like 2 month ago

Calibrating the refractometer is a good idea, especially if you use a 2 part dosing solution. They can raise your salinity.
