If you want to go more organic, or are worried about maintaining a supply of all those chemicals, you can always use compost tea. This allows you to build the nutrient (compost pile) locally and sustainably. Sure, it won't be complete as a store bought nutrient, but there are lots of ways to fill in the gaps.

If you want a really a good book for hydroponics get, "Gardening Indoors with Soil and Hydroponics" by George van Patten. It's my bible. He has some great info on building compost tea and what materials compost into what nutrients. I.e sheep manure is a great overall nutrient (NPK) with lots of the micronutrients (zinc, iron). etc.
