Local Nutrients?

[granth]

Hey guys, I have been reading up on hydroponics the last month or so and have almost everything I need but I am confused on nutrients. Are the nutrients you need not something that you can find locally at a garden supply/tractor supply type place or possibly wal-mart or lowes?

I have read a few places of using the water soluble miracle-gro, but problems arise in strength is the general thought behind reviews. Is there any way to get something suitable for a first run/first try that can be found locally?
