They look pretty good, but may get crowded as they get taller and bushier.
Also, how deep is that bed? Don't want to crowd the roots either.
Fox Farm nutes are good. Just picked up some more liquids: Big Grow, Tiger Bloom, Big Bloom, and some solubles: Open Sesame, Beastie Bloomz, and Cha Ching.
Do an internet search for hydroponics stores in your area. Chances are they will sell Fox Farms. If not, look for Advanced Nutrients (SensiPro A + B).
Good luck and keep us posted.
