Jack's is definitely good stuff, but the tried-and-true Jack's 3-2-1 formula uses the Jack's Hydro Products:

Per Gallon of Water:

3 grams - Jacks Classic 4# 5-12-26 Hydroponic
2 grams - Jacks Calcium Nitrate
1 gram - Epsom salt (get from like ANY store)

Those come in 4 lb. pails... if it seems pricey at $90 total, just remember that it will last for a LONG-ass time. Like maybe 10 small grows! To my knowledge it's easily the most cost-effective nutrient line. I'm switching to that regimen on my next run.
