Yeahhh nooooo.
New, healthy roots are white. Period.
You'll always be fighting this bug now that you have it, but the tea will keep it in check if brewed properly.
Don't use too much molasses and brew for a bit longer are my suggestions. It took 20+ batches of tea before i got it down to a science.
Roots look alright though. Nothing wrong with adding every day.
Good luck
