The imbalance in the motor output signals


I am developing an EDF quadcopter. Currently, I am experiencing an imbalance in the output signals of the motors, with CCW (1,2) being lower and CW (3,4) being higher. As a result, the CW motors are overheating, and the aircraft occasionally rotates to the right. I would like to resolve this issue, so could you please provide some advice?
Thank you in advance.

Without looking at your log, two possible reasons, but not limited to, 1. blades are not at the same plane, meaning misaligned motor mount. 2. Non-self-lock propeller nut losing slowly.
