Brown dots on leaf

We have a little problem with a plant (I forgot the name) in our little planted tank. As shown on the picture, some brown dots are appearing on the surface of it. Growth is generally good, but this detail bother my girlfriend hehe. We're dosing florish and florish excel and the tank is lit by two small PC lights.

Is it associated with a specific deficiency? Too much nutrients? Thanks!

Do you have a top/bottom view picture?

If it's visible through both sides of leaf it could be fertilizer burn (too much nitrates)

If it's only visible on one surface it could be diatom or some algae growth, for which nerites, otos and/or guppies help.
