I think the best thing to do from this grow, is learn what worked and what didn't.
With the current size of those plants, you're likely not going to be getting the highest yield that your lights could get you.
But that's okay. Just learn from this grow. And getting to harvest is a success!
For the next round you might want to work on vegging longer, doing more training and really filling out the grow space.
Your plants are looking great and pretty healthy. It's always awesome to see the plants when they really come into the flowering stage.
