If its been 5 months they are not autos I'm afraid. Not a big fan of autos, I like to be in control, but grew a couple of northern lights for a laugh, and they finished in 10 weeks! I know there are some slow autos, but not that slow. On the plus side, if its definitely a female plant you have, you could take a few cuttings and get more plants. Forget the term supercropping, that sounds complicated when you don't know what it means. Basically cut the top off (watch a video to show you exactly where), cut the bottom two thirds growth off (that's all the leaves, stems etc ) so you're left with literally just the trunk and some growth at the top. Don't do it all at once or you'll shock the plant. Because you said your plant is so tall, most of the lower growth will be airy useless fluff with just one light. Doing what I said will let the plant focus on all the growth at the top, and by cutting the top off (topping) you'll hopefully end up with a few big fat top colas. Look into LST , it's quite easy even for a learner. Hope this helps!
