Are brown roots always bad?
I've only had experience growing one kind of plant previously, but now that I'm mixing it up and growing several types, I notice some of my plants have brown roots. Not all of a given plant's roots are brown, just some parts. They aren't slimy either. I'm wondering, do some plants just have brown roots or is this always an indication something went wrong and all plants should always have white roots? It's amazing how quickly and how much a subtle change in the system can cause the browning.
