I've noticed that two of my plants( have to look up the name but will post a picture as well) have black spots on their leaves. What could this be?

Algae of some kind?
Plant Disease?

It wouldn't rub off so I'm assuming it's something internal, maybe not getting enough of the right nutrients. Or could I be putting in to much fert?

Since the water change the black spots have receded 362036213622 but now my sword is looking kind of funky. I did just get a large spotted Pleco, but I just removed him from a small cave he had gotten stuck in for the past day or two, and the veins In some of the leaves are predominately black. They are still soft tho the touch and not brittle. I read in another post the swords require iron I believe or magnesium?? All other plants are thriving.3623

Most of us are going to need some more information before we can try to help.

What type of lighting do you use and how long do you run your lights for?
Also what are you using for substrate and nutrients?
Are you running pressurized CO2?
