I'm not sure about the leaves curling like that man... Looks like it might be an issue.
Also I was under the assumption that plants could be revegged continuously for many years. I've heard growers say they've kept plants for 20 seasons before and each year they just get bigger and stronger.
No personal experience with that though, I was planning on trying that out this year with my plants I harvest. I'm just going to snip the branches and keep the main stalk up and watered, alive for next season. It doesn't snow where I'm at and the temps are survivable for the plant, so it shouldn't be a problem, we'll see what happens next spring I guess...
