shit herbal that is bad news to hear about your babies getting attacked by an angry grow light,not sure about how you should go about it although i reckon you should wait atleast a week maybe even 2 weeks to let them babies recover from the shock of the grow light attack,and hey fasten that light to the wall good this time and use big fuck off screws,you done good gettin a splint on the worst victim but repotting i aint to sure if that was the best idea unless the roots were severly disturbed
