When to through Canna Boost in the mix

Im currently running the full canna range my plants are 4 weeks old tomorrow, I plan on a 5 week veg, My tent is 2 metre high,

Question is when I start flowering when do i through the Canna Boost in the mix, When I flip to 12/12 or when I see flowers forming around 2 week after the 12/12 flip?
