That is pure nonsense. I use some of the cheapest nutes money can by. No additives and not a single bottle with a fancy label and cartoon name selling for $25. If you go into growing with the mindset that nutes are that important then you're setting yourself up for failure. Just look at all the posts of people with a dozen bottles of all the latest and greatest nonsense to dump on your plants. The Marijuana Plant Problems section is full of them. Crispy fried leaves and nasty looking buds having all kinds of issues even though they're dumping any product they can get their hands on.
If you want max yield then make sure you have plenty of light and a good environment for your plants to grow. I'll put the health of my plants and my yields up there with those using all those products that have been aggressively marketed to naive cannabis growers. And I just use calcium nitrate, a micronutrient blend, and monopotassium phosphate. I can buy a pound of each in watersoluble dry form for what people pay for some bottle of "Magic" that is made from the exact same stuff I'm using.
The cannabis nutrient industry is nothing but a money grab. More money is spent on packaging and marketing than the product that's inside all those shiny bottles.
