More growing energy will go to the other budsites, the light is more of a worry if it got light when it shouldn't be. If it is just darkness during the light cycle, in your trunk, that's like having an overcast cloudy day. Part of nature, no stress to the plant.

As for the physical damage, animals, falling branches, things like that happen in nature too. It would have been better for that to happen before flowering of course, but a few weeks into flower isn't too bad.

You might lose some overall yield, but the plant will make up for it somewhat by putting the budding energy into the lower branches.

Keep her healthy from now on and she should be ok.
