This is my first hydro grow and I am using ebb with12 pot system. I started out with 6 auto ak47 and they just started to flower a few days ago. First question I have is my roots on one plant have come all the way through the bottom of the inner bucket about 6 inches. Even if I did the PVC mod they would sit in the water. I am not sure what to do about the roots, although right now they look white and healthy. Second question is mixing nutes, I am using Lucas formula and I mix the correct Mount for the 40 gallon I am using in Rez in 1 gallon jug. I then pour from gallon jug to Rez. The nutes seem to be crystalizing at the bottom and I am not sure if that is a problem. If it is how should I add nutes to Rez. Any help will be appreciated.
