For some reason my roots (which are all nice and white) have some muddy goop like substance on them. Almost like its nutrients. I'm using a DWC tote and I'm using PBP grow, liquid karma, and cal/mag. All the nutrients are 3/4 strength. The roots aren't brown, they have a brownish goop on them, I sprayed all the roots with a hydrogen peroxide solution, and the plants don't seem to be reacting in a negative way, no signs on leaves or stopped growth, but idk how long the goop has been on the roots, maybe 2 or 3 days? Please any info would be nice.
