It all comes down to what you want, I have seen gorgeous plants produced with no nuts whatsoever. I have also seen gorgeous plants produced with silly amounts of nuts. Rumour has it that organic will taste better, and chemical will produce more yield, but it comes down to way too many things, including the individual plants. Go with a basic 1 part flowering nut from ur local hydro shop. I have heard very good things about advanced nutrients, both organic and chemical. I would recommend Iguana Juice if you have the cash and want to go organic, my local guy recommends CYCO's line of nuts also.
