Yeah, I noticed after I started adding calmag that I was getting the brown tint that I didn't get before. I assumed it was the calmag, but without actually testing this theory, I can't be absolutely positive that it's not the micro. I did notice that there is some "blobs" of discoloration that I don't recognize. Mine were just tinted, didn't show any signs of "blobs"

Either case, the brown tint doesn't look quite like root rot. I've seen root rot many times and it appears to cover most of the lower portion of the root system and appears more mucky/slimey than these roots.

I'm probably doing more harm than good from this point on. I could have him chasing a wild goose with my hydro experience. I'll leave this to the pro's to chime in on.
