Hey kngofhearts im pretty sure those bugs aren't aphids. I have them all over everyone of my plants outside the entire grow, and they haven't been doing any damage. Im not sure exactly what they are, i am not an expert, this is actually my first grow, but i posted a thread about a month ago and put picks of the same bug up and everyone said don't worry about it. so you shouldn't have any problem.
This is a pic that i took, pretty much identical to the bug you took a pic of
