I think we really need a pic on this one. I will take pic's of mine if need be. My first grow was nothing but dynagrow and roots were white. Next 2 grows were GH 3 part and Lucas formula this time, B-52, Cal-mag plus. My roots are the color of my res. Kind of browny red. They also look like they are dragging down some of the rockwool cube they strated in. We need the whole story. Mine are doing very well.
