Kush over is right about the worm casings, they are a really good all around food. Also, once they're more than seedlings you can give them a good shot of organic Nitrogen by making alfalfa tea. Alfalfa pellets are $4.50/ 50 LBS!! around here. I put 1/2-1oz in the coffee maker, then dilute into a gallon of water. I've read that it also has some good trace nutrients, but I've heard that it is not recomended for use during flowering. They DO love it in veg, and so do jalapeno peppers, BTW
