Mold or Dust on my Soil?

That looks like the same issue I was having and what I read is that it’s that mold you said the leaf septoria shit. I read you can leave them on just don’t touch the bad ones and the good ones.

I seem to have a white fuzzy mold on the earth as well. 3x3 grow tent, normal temp. & humidity. Circulation fan going.
Is the peroxide & water mix 1:1?
