To be honest, I ask as I have been watching the Cannacribs episodes and they all seem to use the whole nutrient lines on it!Why would it? They should have everything the plant needs. If they don't then don't buy that brand. General Hydroponics Flora series is a 3 part nutrient and people have been using that for decades without any extras. All the "extras" only showed up because it's easy to convince some stoner to buy another bottle of something.
No other plant has fancy nutrient "Lines" with a dozen plus bottles that you need a 2 page feeding chart to use. It's only in the cannabis growing world. Some slick marketing, amazing claims, magic in a bottle, etc... No group but a bunch of stoners would fall for all the nonsense.
Those fancy packs with starter this finish that and a dozen bottles in between might look cool with the shiny labels and cool names but the plant doesn't give a damn about all that.
I suggest you spend a little time researching basic plant nutrition so you understand what a plant needs and why.
