Holes in anubias and crypts

I have been battling holes in my anubias nana and crypt lucens for a while and cannot figure out the problem. The holes are about 1-2mm diameter and sometimes much larger and appear in old and new growth. The tank has shrimp, tetras, otos and some pond and the common orange rams horn snails.

I thought it might have to do with K, Ca or Mg but I dont think so anymore.

This tank (30g) is med-high light with CO2 injection .

For ferts, I dose about 15ppm NO3 from KNO3 (9.5ppm K), 5ppm K from K2SO4, 2.5 PPM P from KH2PO4. For traces, I currently have the usual 1tbs plantex into 500mL and dose 12-18mL per week. I have dosed as high as 3x this before.
I ALSO (didn't in the past, but have for the past month or two trying to fight the holes) Seachem Equilibrium. I have a mix of 1/2 cup in 1000mL (no it doesnt all disolve in 1000mL and yes I have to shake it up and dose a suspension to the tank) and dose 1oz (30mL) at my weekly WC (40-50%). THis equilib dosage gives and additional 0.04ppm Fe, 2.03ppm Ca, 0.8 ppm Mg and 6.37ppm K .

Any ideas out there?

Re: Holes in anubias and crypts

Describe the holes, are they fresh cut or have necrotic decay?

Try not doing a water change and see if you see an improvement.
Just try it for two weeks and see.
See if there is something related time wise to their appearance to the water change(cold tap or no dechloro etc).
