I'm sure some may cause staining, maybe in Dwc, but I wouldn't suspect it in a flood and drain or drain to waste. I've used gh flora for years, but never flora duo, flora nova or liquid karma. I do know people that do use nova, but in drain to waste, so the roots are white as can be. Dwc may be different though, I don't have experience with those products in Dwc.Another growers root staining
