NPK For Flowering, and when to start feeding flowering nutrients to the plant.

[SaltRushMore]

The plants vegged for 10 weeks
The Plants are showing pre-flower pistils

Currently I have some nutrients that are listed as 9-4-12.. The Nitrogen and the phosphorous look to be a little high to me but I was wondering if there would be any issues if I moved forward with this product. Also, Once I switch to 12/12 can I start using the Flowering nutrients right away?? Any advise would be greatly appreciated, Thanks.

No idea how will perform but "Coated" means slow release...
The only thing that could bother you is the slow release of unknown amounts of N during the end of flowering...
