Hi everyone,
My amazon swords get some holes on both old and new leaves. What is the symptom for this?
Sorry I don't have a close-up pic. The first pic was taken when the swords started growing (no holes) and the last one they grow big but with holes.
Please :help:

A nutrient deficiency will cause this. Perhaps potasium?

Blueiz thanks. Should I add NPK rootab or dose purely KNO3? What I am currently using is an unpopular liquid fertilizer Whitecrane Plant Plus still I am happy with this fert dosing way daily 1 drop 1 gallon and no big issue with algae so far except for the pinholes.
KNO3 will work, it will supplement Nitrates at the same time. But if your nitrates are high already, nu-salt will work too, its KCl.

Thank you Riiz. Will dose KNO3 accordingly. Problem with me is I don't have a test kit and I have never done any test. Would try to obtain a test kit. I also have the same issue with Anubias and new leaves are not growing in the correct size - remain small comparing to the size of the leaves obtained from Lfs.
