I mean, I’ve grown many different ways over the years…. I don’t think I gave any bad advice though, if that’s what you’re inferring….Pretty sure @Frankthetank(correct me if I'm wrong) uses Promix which is a different animal than soil. It's mostly pete, so it doesn't have a lot of nutrients in it to begin with. So, he has to fertilize regularly. Soil has nutes and if it is a quality soil, no need to feed till it starts to deplete them.
