Take a look at my plugs
I just changed my plugs tonight and noticed that the rear rotor looks to be running rich and the front rotor is running a little lean. Do you guys think it could be an injector making the front to run lean?

They look normal to me.
The trailings will always look "richer" due to the fact that some fuel gets shot into the hole first as the rotor sweeps around and the smaller hole through which it fires through.

The front plugs look good for an NA. The rear plugs look pretty gummed up. Couple of thoughts:
1) Bad plug or bad plug wire? Loose boot connection?
2) It's not the coil since the leading plugs use the same coil.
3) More than likely, it's an injector problem. Bad spray pattern or leaking.
