Personally, I don't care if you use organic nutrients or not. you can use them forever and never hear a peep from me. But inferring they are "better" or more "pure" will get my hackles up.
Organic means (or at least defined by common usage) "derived from living matter" or "denoting compounds containing carbon". But i think the definition has changed to: "shit we made up so we could hype our products and charge more."
Here's an example of why organic doesn't matter: if it has 7 protons in its nucleus and 5 electrons and an atomic weight of 14: it is nitrogen (which is organic btw - not sure why you singled out N as being bad) regardless of its origin and therefore indistinguishable from ... well nitrogen. So whether "something" is created in a lab or created in something organic it is still the same "something". This is especially true for common elements used in nutrients. Same goes for people vitamins - not one iota of difference between "organic" vitamins and other vitamins other than "organic" on the label (and very tellingly - the price). Same directions, same usage, same recommended daily requirements and most importantly, same results from taking them.
and as for "there is a difference to some people" i'm assuming you mean taste and flavor? i'll believe that after a series of double-blind taste tests. But here again, it doesn't matter if it is true or not - if you want to use organics go ahead. If you tell me they taste better - i'll ask for proof. No harm in proving claims, right?
I apologize for coming off harshly and i do understand the emotional and spiritual connection we make when using "organic" methods, nutrients, etc.. But there are some disturbing trends related to the organic craze. Especially when it comes to genetically modified foods and while that is another topic - the origin for the mistrust of GE food is similar (if not identical) to the pro-organic arguments. The generally bad science, anecdotal evidence, and voodoo pharmacology that surrounds organics is another very disturbing trend.
But again, to be clear, i am not saying you shouldn't use organics. Hell, i'm not even saying they might not be better but the evidence just isn't there to support that claim. sorry.
