Something interesting happened after installing my new autocob. I have my big plant split directly between the autocob and a Mars 300 60x5,. The side of the plant under to Mars is growing over toward the autocob quite noticeably showing a distinct hook on the ends of the colas toward the autocob. That is impressive! Just cropping up the last couple days, the Mars side of the plant is showing some Ca def problems, and the autocob side of the plant shows no defs. Damn near draw a line down the middle. On the main, the fans on the Mars side showing symptoms and directly on the other autocob side the twin fan shows nothing.
