calmag has never colored my roots that I have noticed. Micro does and bloom enhancers do for sure. But then again I do use H²O² as a normal additive a few times a week and that's why maybe I don't notice calmag changes the color of the roots. But by checking for smell that's the best way to know if it's a problem or not.
Zandor Reviewed by Zandor on . Identifiy the problem ~800 PPM CalMag + FloraNova Grow PH @ 5.6-5.8 at all times -- Skunk #1 -- These are clones under @ a little over two weeks of vegging - I did find algae in the res, so I changed nute solutions last night -- They are under 18/6 cycle -- Plants are getting progressively worse as time goes by. This seems to mainly effect the fan leaves... Rating: 5
