One thing I learned from Tomatoville is that hydroponics stores are a great source of organic gardening stuff, so I googled athens ga hydroponics and found this source

I've always used the liquid seaweed concentrates, which I find at nearly every garden center around here. Seaweed adds trace minerals.
Alfalfa is a great N source.
