I grew out off hydro a couple of times.Make sure ur water dosent get to cold thats important for the roots so they wont clog up and will get the right amount of nutes. Wen u add ur nutes u should mix them a gallon jug and dilute them real good then just pour it in the resivor and mix it wit the rest of the water. Make sure u change ur water every week and half during flower. And the last week and a half to 2 weeks b4 harvest dont give it any nutes u should flush it so it wont smoke harshnew root growth and its nice and white woohoo its coming along
