Spark plug reading help needed

I am currently running a cam only (BTR stg4) and bolt on setup, with ngk tr6 plugs. Seemed to be a little off, so I decide to try a set of tr5 plugs pictured. Need some help diagnosing what is going on here. Concerned about cylinders 4 and 5. Any help is greatly appreciated!

There doesn't seem to be as much carbon build-up on 4 & 5 as the rest of the plugs. Could those cylinders be running lean?

Just a guess.

Wow...really? They're not going to be exact perfect. When one is bleach blonde white or black n gooey. ....then I'd be concerned.
