I use 20/4 for my AK47 auto's. But I've heard of people using 24/0, and 18/6.

I have about 9 more days till harvest. There not as tall as I'd like, but that's most likely due to the problems I had in the beginning. The cola's are a good size so obviously there's some good about using molasses that I didnt have on previous ak auto grows.:thumbsup:
