Hello Saeid,
The Holly Grail, well I'm not sure there really is a Holly Grail of hydroponic
nutrients (per-say). Different plants have different
nutrient requirements, so there isn't a one recipe fits all plants (like a one size fits all shirt). If your going to make your own, you'll probably want to make them specifically for the plants your growing, rather than just a general use nutrient/recipe. Also if you plan to make your own nutrients, be prepared to learn some chemistry. Even though I haven't ventured into making my own nutrients yet, many people do. I do have some things I can post that will hopefully help you.
Here is nutrient recipe for growing tomato's from the University of Arizona

Here is a free nutrient calculator

Although I haven't read them yet, here are a couple of books on my list to get
Hydroponic nutrients : easy ways to make your own : a cultural handbook (3rd ed., revised.) by M. Edward Muckle.
