Dulling Root Color?
Ok, replaced the spent solution with clean water and let it "rinse" the system for 24 hours. I emptied that and added fresh water with full solution this morning which is at the 3 week mark.
I think it was time as some of the new growth on the basil is lighter green than they should be.
I also notice the roots of both the lettuce and the basil are not nearly as white as they have been.
I do not see any other signs of distress in the roots or the veg growth.
Should I be conserned with the dulling of the roots from white to almost a brownish haze?
Thanks in advance.
