Roots don't stain. If they are brown, algae.

...ummm, apparently you have never used GH Flora trio-turns roots brown like they spit tobacco.
my solution temps are always in the 70's and sometimes see low 80's-been doing this for the past 3 seasons with brown roots.

I have never used them.

Never witnessed it. Seen them change "shades" from solution, but nothing I would ever call a brown. I don't think I would use nutes that stain though. Nothing wrong with the nutes, I like to use roots as a diagnostic.
