Mr_SCROGanswered grow question 3 years ago I think Your plan is good, bro.
Your girls will grow more 10-15% of its volume on a flowering stage. Just see them wouldn't bekome too large for Your grow tent.
Defoliation is good to go above one week before flowering, or during it (3-4 week) - when You can see, where the flowers will grow.
Best wishes!
