"Miracle Grow Feeds up to four months" Organic

Is this true, and can I say I am growing Organically if I use this stuff. I am by no means a proponent of the Scott's, or the Miracle Grow brand, but it is convenient, and some time much cheaper. I went into the health food store the other day to by rice, you know, the organic type, well it was more expensive than steak. I just think some times....

Oh my current fertilizer needs are being fulfilled by Advance Nutrients (Heavy Harvest types as I am a outdoor grower), any other advice, or fertilizers I could use would be greatly appreciated, thank you.
