If that broken stem doesn't look like it's recovering, and the buds still need more time. You can cut the branches so you have a lot of stem, place them in water and finish them in your indoor tent.

We ran into this last year, wind broke one of our girls. We tried to tape the stem where it split at the base of the stem. Which looks to be just like your situation. The broken stem did not mend well from this quick fix. If our indoor tent was set-up we would have tried finishing that stem inside.

Again not sure that's even necessary with your plant, but it's an option if you need it.
