Nutes/ppm question

Hey !
I use GH flora series and Cal/Mag.
Milwaukee MW802 (700ppm)

I want 500ppm for veg but when I use 1/2tsp of Micro, 1/2tsp Gro and 1/4 of Gro I get 480ppm including the 70ppm from the filtered water. Which is where I want it for veg stage.
But, adding the Cal/Mag gets it to 930ppm. (Yes, I mix cal/mag first)
So, do you calculate your ppms with or without the cal/mag ?
