During veg, you're going to want a higher nitrogen ratio. (nitrogen being the first number - 5-1-1)

They sell this great stuff at wal-mart called Alaskan Fish Emulsion. Smells like complete and utter ass and I wouldn't under any circumstances leave any of it laying around my house mixed with water.

What I'm saying is don't store it.

It's 5-1-1 perfect for veg.
