If the plant growth is unaffected then don't worry about it.

Answered your own question high nutes will cause this.

Also most nutes do have brown/black colour which can stain your roots.

As long as keep your Res temp an there is no slime an plants are healthy I wouldn't worry

I appericaite the responses. the root r startin to look white todayand a few of them r startin to fish bone so to speak. kiss-assthanks again

how fast is the plant supposed to grow? I kno they usually start off slow due to the transfer. the lady has been in there for 10 days now. can any1 tell me how much growth I should expect? im just new to this and just wanna do the best I can.. thanks again
