Hello all:stoned:i was gone for a couple days and came back to some good growth and long ass roots, 3 of the 5 drippers are off. Today is day 20 from sprout but im still concerned about the top right plant as it seems to be slightly dry and wavy, also noticed a small hole with yellow rim in one of the leaves? should i foliar spray them? also my ppm still hasnt moved it seems to stay in the 900 range all the time? any comments welcome
