Was running 20 on 4 off. Did raise the light 4 inches. Confusing me because the 1st ak47 I harvested had about 10 % amber and nicer denser buds.. but she wasn't in the tent as long. This 1 took forever, never did show any amber and foxtailed like crazy.. I do believe light intensity was too hi. Other 3 plants were very short and bushy. This last one stretched more for some reason, and grew very odd structure.
