Put a screw in the lid of your bucket and find something to try to pull her down like some thin rope and tie it to the screw in the bucket. I'd try that b4 topping. If that dont work I'd say try to top her.
i managed to pull down the main cola and some of the side colas too. it is now almost half height. but only issue is.. its still stretching like mad.
i think it has started to flower. i can see some little pistils or... they look like pistil, could be very thin leaves.
