Agree 100%
If it was a tension issue you would see it happening with the areas that were straight as well as the curves. Because it is only happening with the curves I agree that it your hand speed is too fast for your machine speed.
It's usually best to increase the machine speed as opposed to decreasing the hand speed - but your hand speed should decrease a smidge when you go around curves.
