Im currently growing 3 auto ak47's, my first ever grow. It was very obvious when mine entered what is widely termed the 'vegetative' stage of growth, it went from having two real leaves above the cotyledons to having four leaves with the beginnings of several more 24 hours later. What is being refered to as the vegetative stage as far as I can tell, is a plant that has moved on from its first two leaves into more full growth but has not been put on to 12 -12 lighting which would cause it to flower.
