Coffee grounds means what is left over after you brew the coffee. To keep your grow strictly organic, you should only use grounds from organic coffee. It may seem like a hard line issue (probably is) but might not be as conventionally grown coffee can have fairly high amounts of pesticide residue.
I try to stay away from anything in the Miracle Grow line, and Scotts too for that matter. I don't trust much that comes from a corporation, especially the stuff they call organic, but that's just me. I always try to use the highest quality potting soil I can get, like Whitney Farms or Black Gold if you can find them. It costs a little more but pays off in richness and soil structure. Kinda helps fill any cracks your fert program might have missed.
