The adding the cal mag came from their magazine. I just have to dail in on the right mixtures and measurements of each. They have a calculator app as well as one online. Depending on your experience
advanced nutrients recommendation are different.
Always feed by plant response. Guides are just that guides.and you can't mix advice with one nutrient to another in some cases... Like this.
Sensi coco is designed to have extra cal mag for coco in it. You don't need to add. Doing so can lead to other issues. Of you calcium gets to high it will lock out other nutrients and you will see deficiencies then.
Imho as a first time grower stick with sensi a and b. Unless you find someone like
@TheBioMaster who has experience with it and can direct how to use additives with it.
You will have a far better outcome. Like I said additives make a small difference and usually do more harm than good especially with a new grower they usually end up costing quality and yield.
Unless running very high light with a dialed in grow you wi benefit more from not using them until you understand them on a nutrient level. Not what the bottle says.
