Ya I think nutrients help in some ways but not like tripling in size and weight. If I could only buy goodies for my soil or add store bought nutrients and fertilizers I would take soil amendments all day. I have never really used nutrients. Just water. Bloom nutrients that probably don't make a huge difference. I grew up watching my dad's friend grow tons of plants and all he does is water them. Plants them right in the dirt. He gets 15 footers easy maybe more. I mean his dirt might be good but it ain't fuckin magic soil. I now live in colorado but grew up in nor cal and saw my share of outdoor growers. They didn't use any of the commercial nutes. Compost and maybe bat shit. That's all. Ten pound plants. Anyways that is just my personal experience and what I have witnessed. People forget it's not a competition, you don't win anything for having the biggest plant.
