I don't know what plants you are growing, but to the best of my knowledge there are no plants that should normally have brown roots. I had a problem with the roots of my strawberry plants turning brown last summer also (see attached pictures). I E-mailed General Hydroponics ([email protected]) the pictures and they said it looked like the nutrient solution was two warm. It should be between 68 and 72 degrees consistently. I don't know for sure that this is your problem, but it's the first thing I would look at.

My strawberry plants also looked healthy but were not growing as fast as they were. I started adding ice to the nutrient solution to cool it down and the roots started growing back white and healthy again in about a week (also in attached pictures). Another side affect is the flowers will start to turn yellow and fall off. This is a survival instinct by the plant because it takes more energy to produce the fruit.
