  2. Burnt perlite? stained perlite?
  3. Probably just tiny particles of soil getting stuck in its pores.

  4. Well the perlite is fine on the bottoms it's the top just looks burnt..
  5. New perlite lots of times turns yellow/brown almost burnt looking on top of the soil, while what's under the surface doesn't. I do not know why. There's tons of threads asking the same question and just as many different answers as too why. It's fine.
