canna A+B in coco flowing nutriient yes or no

I have had great results using canna a+b right the way through from veg to flower,never using any additional additives during flower. Like all out there i am looking to gain any info i can to improve my grow. Any advice would be much apppreicated.

I use all canna nutes. A + b all the way from veg to harvest with rhizo and cannazym. During flower I also add cannaboost up til flush and a week or two of pk13/14. You can find cheaper alternatives for flowering nutes, but I'm sure if you add supplements during flower youll see improved results compared to only using a + b.
