If the bow is tuned properly then lowering the nocking point is bad advice. You never do that.Once a bow is tuned you leave it alone.

A slight change in anchor point could help the situation. It doesn't have to be drastic. Maybe 1/4" to 1/2" would help immensely. I'd say you would never even notice the difference in the feel of your anchor. You just need to move your peep and kisser up the string that little bit.

Or, ar Arthur said, If you're not hitting anything then don't worry about it. Many times we archers tend to think too much.
