Keep things in perspective, I do bonsai and cut 1/3 - 1/2 of the vegetation and roots away every year of two. They take a few days to a week to recover then they take off. Cannabis is a freaking weed, lol. It will be just fine, it's just a matter of how long it will take to recover . This is much more of an issue with auto flowers but looking at your beautiful plant and the pot it was in i really think your lady will thank you in the long run.
