Gelato hydroponics

Last week of veg. Next week the plant will be put on a 12-12 light cycle for Flowering. Things are looking good, I've separated the stems to give lots of room for air/light and bud growth when the time comes. I decided to show a picture of the roots. I've always had them turn brown on me and I've just chalked it up to the nutrients changing the color. The leaves are healthy and there isn't any slime in the bucket or on the roots.
