Am running a flood an drain system. Notice since I flipped girls to 12/12 lights the roots are getting I little dirty looking. They still look fine up top am growing fast. Am using the Canna Nutes A&B an also rhizotonic an cannazym. Anything else I should be doing to keep the roots healthy. Cheers
I'm not familiar with your particular nutes, but mine stain my roots. If there is no slime and my pH is stable I leave it alone.
