Are ready for flower phase?

I would finish out the week and start next week 12/12. I usually continue to use Grow nutrients the first and second week after flip because they will still grow vertically and require nitrogen during this time. You can add a little bloom nutrients as this will promote bud site development (secondary/side branches) the purple is blue and red combined as is the most power and what you want to use for flower not just the red. You can veg with blue red or purple but you want to flower with purple always. Hope that helps and happy growing!!!
