Stem Healed Enough to Flower plants?

Yes :) You could flip her the plants dont heal overnight she will heal anyway no matter what stage your in. people can bend plants in flower if they get to close to the lights its no advisable but sometimes you dont have an option :) But yeah flip those lights baby lets seem them flowers :P

If you see that it might break, you can, for example, reinforce it by nailing a wire to the stem and another to the branch as if it were a staple. I've even gone as far as literally screwing the branches on mine. By the way, saliva is a very good healer.
