I'll second the Gaia Green recommendation. Mix it into your soil, water with plain water, and let biology do the work. No pH'ing, no mixing bottles, no measuring. It's changed how I grow. For anyone starting out: General Hydroponics Flora Trio is the safest bet. Available everywhere, tons of tutorials online, and it just works.

Jack's 321 is insanely underrated. It costs like $0.10 per gallon of nutrient solution and it grows just as well as the $50/bottle stuff. I switched from Fox Farm to Jack's and saw zero difference in quality.

For flavor chasers: organic dry amendments beat synthetic every time in my experience. The terp profiles from living soil are noticeably more complex than from bottle nutrients.
