The flower looks gorgeous! Everything is dependent on factors that you know better than we do, as we cannot see your diary and can only make educated guesses. We don't know whether you are using soil, hydroponics, or another method. We also don't know the type or amount of nutrients you are using.
Personally, I would guess that you should add extra blooming nutrients, as the flower is currently blooming and will require a significant amount of phosphorus.
Good luck buddy.
