Perfect holes in Amazon sword

[Spencer1044]

Okay I'm not certain but I'm pretty sure one of my mollies is chowin down on my Amazon. It has a bunch of perfect little circles on it. It has some minor hair algae on it but I'm pretty sure it's the Mollie. It take good care of these plants so I don't think it's anything wrong with the water ph is 7.0 ammonia nitrates and nitrates are all 0 if not 0.1 so water is good. Any ideas what it could be

Looks to be a deficiency,possibly potassium?

Could it be fish poo? I know fish poo will burn through the leaves of plants

Okay well I just put in new root tabs see what happens

It's possibly a potassium deficit. It is known to make (black) pinholes on the leafs of aquatic plants.

To be honest I think it was the root tabs cuz I havnt changed them in a while but if I don't see any improvement then I will go buy more furts

Could be the issue, tabs often contain a mixture of iron and potassium
