Mixing different brand Nutrients

I am just about to switch to 12/12 and im using Ionic coco grow, I have ordered Hesi coco bloom and want to use this during flowering but as I need to give some grow and some bloom nutes together will this be a problem?

I was also thinking of using Canna PK 13/14 with this too, Any opinions?

Cheers

to keep things simple i would stick with one line. Certain nute lines are designed so that the additives will make up certain levels of minerals at specific times in the cycle. So i woulod find the line with the simplest recipe and stick with it. I have been very happy with my House& Garden that I recently switched to now that i can get it in canada. I here its #1 all around the world.
