What do you do w/ plants that are developmentally delayed?

I have a Jack herer autoflower that is not growing very fast at all. The plant has some serious genetic issues. I'm growing outside and have moved all but that little JH out. Is it worth trying to make her comfortable in the hopes that she will grow? Or should I just write her off and move on?

Experiment with that one! I'd just do some crazy training see if it lives. If not.. oh well.
