i'm a little confused as to why you'd grow 4 times and never harvest but let's let that go.

as locomark said, you can keep a mj plant in the vegetative state almost indefinately (10 - 15 years and more)

in fact, many breeders do just that, some have mommas that were planted from seed in the seventies.

that funny leaf pattern you refer to might just be the plant letting you know it's mature enough to display sex (early in the life cycle the nodes grow out in a symetrical pattern, once mature, the plant starts growing asymetrically, ie alternating nodes)

anyway, i hope this helps
