Let me first say that Organic is purely a marketing term as it is used now days - the original definition of organic is simply 'contains carbon.' Show me a non-organic plant - impossible.

I've had fine results using a bare-assed 3-part series from GH and AN. Both companies truly don't have half a clue about true nutrient requirements for multiple plant types, though I've demonstrated mixtures to both companies. They just ignore real science and keep on going with their marketing (like Advanced Nutrient's BS about phosphor overload - learn basic biology, nimrods! ATP is CRITICAL for plant energy and ignoring it during bloom is a stupid STUPID mistake.)
