hey there, sorry to hear that ! if it's only been a few minutes or a few hours try using duct tape (opaque tape) and litterally put the two together and tape it up. Hopefully it's not been too long and in a few weeks it will be fully healed. Basically you're gonna miss a cola and it will shock the plant a bit, just keep in veg longer or top another cola, no reason you should loose more than you're comfortable with loosing. Hope this helps ! 🚀
