I grew Walter White autos my first auto grow with pretty hot temps. It was due to summer heat issues....these plants had more issues than any grow I've ever done and they still came out phenomenal...Just 20 mins ago my girls sister said it was the best bud she has ever smoked. Now granted, I didn't get a ton, but its killer. Also, with a single point light source like an autocob, you are best keeping things more even. Try again with some different genetics...Also, definitely looks like a Mag deficiency, but I've never seen that.
