She should be fine, I had a similar incident not so long ago. As far as I see from the picture it's bent and broken but it wasn't ripped off, so the flow is a bit tightened but if there are no other problems like PH and overfeeding then you won't even remember that this happened 😀 Be more careful next time though.
Oh, and if the same thing will happen to you when the plant is a bit older - broken branches can be fixed with tape. I also had this many many times. A previous week last time 😁
