Quite a bit of what I believe to be algae. The leave and buds look fantastic for their small sizes. First thing was to change the res and replace with hose water with the addition of hydrogen peroxide at a rate of 3tsp/gal. Roots look like they are coated with a brown film over the roots. Once they are clean I will continue flush with Flawless Finish. Despite the buildup on the roots the plant is showing no signs of weakness.-Update: the dark film never disappeared!
