In the pictures below there are about 1 tiny hole per plant and bite marks/holes on the edges of others.
The only change I made was remineralized my water change water with potassium bicarbonate/calcium carbonate/sodium bicarbonate and added magnesium sulphate to it as well. In the past, I just used sodium bicarbonate and left the GH minerals out of the equation. Water up to 4dkh and 6ishdgh
The holes are all in older leaves which suggest a potassium deficiency, but as I mentioned I added about 40 ppm of potassium in my water change (which I hoped would tie me more than a few days) ... so I am thinking it may be too much magnesium and calcium that is affecting potassium uptake.
Any ideas: without doing anything too quickly, I may not remineralize the GH on the next water change.
As a final thought, my nitrates have gone down to around 10ish and I haven’t dosed it up: could this be nitrogen deficiency. Note is in crypts and I use root tabs.
Or are my fishies having a snack?!
