I would flush those roots out with good PH'd water. what ever looks brown and rotten, cut out. Also change out RES, then add some Hygrozyme to you RES. This is just IMHO. Best to get another Opinion. Make sure to clean your res, pumps, and everything.
How sure are you? To think, is kewl, but I don't want to scrifice any much more than I have to. Choppin back the roots could well slow the current progress, which has been more or less constant so far. My Dr said root development stops 3 weeks in to bloom... I'm beyond 3 weeks and wonder if chopping back the roots will ever be replaced with new growth with relatively little time to spare??

I'm flushing until the end of this week. I will probably scub the reservoir and top trays again before I commence feeding at the weekend.

Do you have a few pictures of your system?

Is a link to to a couple pix of the setup. I'm at such a loose end with regard to the roots. So many slightly different opinions. I brought the doctor round to inspect the ladies and the Dr said I have to cover the top tray. I wanted a few opinions, just incase someone else has completed a grow under the same conditions and noticed that the root colour didn't make a difference to the over all harvest.

Do you have any contributing notes that describe how the environment can be bad when the trays are covered?

Thanks!! :thumbsup:
