For the past month two months, any new leaves put out by my swords have been small, pale, and with sizeable holes. In addition, the leaves sometimes look almost pink. My fast growing plants (Wisteria) are not having this problem.
At first I thought potassium, but these holes are much bigger than the K deficiency holes I see on plant pictures on the internet; plus I dose consistently with potassium.
I'm pretty sure this not a result of fish eating the leaves because they are very pale in addition to the holes, almost white.
I've tried root tabs for a couple of weeks, but no change. I have also noticed extremely reduced growth, with pale leaves, on my aponogeton.
Water parameters are pH 7.1-7.2, kH 3, nitrates measure 0 with an aquarium pharm test. I tested this twice on two different days. Could this be a nitrate deficiency? It's hard to believe with ~20 fish in a 55 gallon. I've been DIY CO2 injecting, but am still fiddling with my DIY apparatus for dissolving more CO2 in the water.
Of note, I'm currently having a signigicant BBA algae outbreak. I'm not sure if this is sucking up the nitrates along with my exploding Wisteria or not.
I know there are a lot of knowledgeable plant experts out there and I'm hoping you can give me some insight.
Thanks.
