Hello @bikerkiddo, You wrote a great comment. You sound like you have some garden.
About your bok choy, I have never grew them. I do have seed for them though. Those worms you are talking about sound like the ones that eat at my tomato plants. When I see that leaves are being eaten then I look for the big worm that is hard to miss.
Also I just checked what might be attacking your bok choy. Click here to see what you can do.
Keep growing food in your great garden.
