What size light are you going to flower these under?
Watch herculeeeez root damage. If their are dead roots then you might want to get a zyme product. i.e. hygrozyme, cannazyme. It will turn dead root matter into something your plant can absorb and use, instead of sticking to your other plants roots and causing root rot. If temps are high in your rez you might want to think about how you can cool it down. Overall, looks good.
