Stress slows-down normal growth. Depending on severity of the break and strain stability, and your ability to leave the patient to heal. (not make it worse by throwing additives and crap at it) Healing a broken branch should only take a couple of weeks, but she should resume 'normal' growth soon enough.

I'd take them as far as they will go. You've gone this far, why quit now?
Not that you were intending to feminize seeds, but when someone does attempt to feminize, first they have to stress the lady. You've definately done that, so keep an eye out for nanners. If this was a stable strain, any pollen they produce, will produce nothing but females.

A couple of way's to looking at it if she does turn on ya:
1) If she does start throwing-out stress nanners, all the seeds will be female, which many gardeners pay top dollar for. This is a different situation than someone all of a sudden finding unintentional nanners on a genetically weak strain. You know the stress you created caused the nanners.
2) If she does self-pollinate, the yield will suffer as she switches into a seed-set phase. More seeds equals less yield.

Even if she doesn't hermie, the yield may (will likely) suffer a tad, but the trichomes will still develop and mature. So if harvested early, you are likely losing yield and quality.

I try to always recommend folks taking their grow to to the bitter end. There's no education like personal experience.

Or, cull 'em early and start over. Or re-veg her. :thumbsup:
