I didn't buy Advanced Nutrients brand nutrients because all over the internet salty retards always say it's expensive snake oil (to be fair some of their extra products sort of are).
So I didn't even look into it. Turns out the base nutrients which is all you really need are some of the cheapest on Amazon, arguably the best out there, and they automatically control the pH levels of your water for a week. Automatically controlling pH levels is amazing and worth money by itself IMO, because I have to check that everyday and sometimes adjust it which is a pain in the ass.
Plus they have funny branding.https://www.advancednutrients.com/products/ph-perfect-grow-micro-bloom/
