Hibiki's c.lk XX qcf + mp

I’m having trouble canceling the qcf+mp after the crouching lk. What is the timing needed to succesfully cancel in the slash?

This combo should be pretty easy actually…her main bnb:

c.lkx3, c.lp, qcf mp

For: c.lk, qcf mp…I think that your probably pressing qcf mp to late…do the rotation during the c.lk, there should be no pause, mainly all in one motion.
