Well rule out GH/K.

I do not place confidence in any iron test kit. I do place far more
confidence in adding a certain volume of a trace mix into a known volume of
water. That is a much more accurate way to dose traces IMO.

My bet is CO2. Go back and check it AM vs PM and compare to the chart.
High K will not bother this plant. I've had K at 50ppm for some length of
time. Never saw any issues with that and I kept many species.

When you are stumped, do a big 50% water change and add the nutrients back
into the tank. Be patient and repeat.
Add after water change:
1/8 teaspoon of KH2PO4
40mls of traces
Make sure the CO2 is 25ppm or so.
Wait and test to see the NO3's and PO4.
Add KNO3 if needed or PO4.
Add traces every 3rd day or so. Don't worry about the tested iron level.
Feed your fish.
