Hay jman214. Dont change a thing. Autos dont need a light change and especially dont go 12/12 unless you want a stunted crappy plant. Auto's need at least 18/6 but 20/4 is best. Nothing against teo420 but apparently he has never grown an auto. Come and check out my autoflowering grow group. You'll get the right advise there dude. Just click on my avatar and at the bottom is my group link. Check out my auto grow pics while your there. Several strains to look at. Hope to see ya there. Later dude
