Well if growing, malting and roasting your own grain for a brew this early on in your brewing life, I strongly suggest you purchase home brew software so you can accurately write and tweak recipes to see what the changes do.
I started right off doing all grain, building my own crusher, writing my own recipes and buying ingredients in bulk, but I sure as hell wouldn't have started growing, malting and roasting it, too.
You have much to read and learn about, so very much.
