We'll I'm not a bio-chemist (not trying to misrepresent myself) I have a biochem background (1 year) and 3 years of organic, inorganic and general chemistry (all college level). I also have a year of microbiology. (2 semesters) I've got an RN degree, and was planning to become a nurse practitioner (APRN) which takes the same level courses of say a medical doctor, a pharmacist, or perhaps masters level MA. A biochemist is much more in depth, for certain, and would have taken those classes and even more. Probably shouldn't be even saying this, actually. (kinda pins down who I am).
That said, to each their own, and certainly everything can be done with a simple 6 pack of nutrients, and I suppose many do. That doesn't change the fact that there's many different ways to grow, and for me, growing organically has been far easier than growing chemically, but as I stated before, I tend to do a bit of a hybrid of them, staying in neither camp, I use what works, period. Also, some of them won't probably use a salt when it's needed, because they have this ignorant "preconception" it's not "organic", which it absolutely is....
I suppose a lot of people have problems with organics because of the sheer complexity too it, there's far more organic choices than inorganic ones, and all of them come with certain caveats, strengths and weaknesses, or perhaps even cross over's. Salts are likely more simple and straght forward for the newer guy, but people like sub-cool made it really easy to figure out..
Also, for me, I've got over 10 acres of land in the Cascades, with tons of thick rainforest soil, and glacial dust, even a glacial creek. I have plans in the spring, and learning this well will serve me for years to come. I don't want to have to tend something that's 50 miles away twice a week, because I'm using organic salts only, that's just not feasible, or realistic, whatsoever.
I've been growing thousands of seeds because I have a plan in mind. I think we just are thinking along two different ways of doing something, and you've got a little more specialized approach, perhaps. Just because someone don't have a bunch of letters after there name, doesn't mean shit with cannabis. I've got a friend who's been doing it for almost 40 years, and nothing else. He's a freaking genius in my eyes, but he see's me smart in the more traditional sense, I suppose.
