    Probably just tiny particles of soil getting stuck in its pores.

    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.
