Supercropping does amazing things, mostly because you'll get a proper canopy... Gently pinch, bend over 90 degress or so, and be sure to gently secure it with ties or it will bend right back up... You should see the end turn up towards the light by the next day.
I've grown tall plants like that before, but you can see in the pic, there is not nearly enough light down at the bottom. you'll only get one good cola out of all that unless you top that off, get more light, or supercrop it I think... Will be worth it and then you can get those lights closer.
Assuming this is sativa heavy, you've still got at least seven eight weeks to go, plenty of time to super crop it...
