Low rpm, Pixhawk 4 + Tekko32 F4

Throttle maxes out to an idle speed starting from very low speed after arming. I use actuator test and rc to test. Need some help troubleshooting.

My setup is Pixhawk 4 + Tekko32 F4 4in1 60A esc + 6S battery. I am not using PM07 but directly connecting PWM out to esc motor wires + ground. ESC is powered through PM02. ESC_Status data is available through Telem 2 but no current signal. Tried using ADC for current only which did not work either and I do not know if this is causing the problem.

Looking for some tips.
