I agree with Glenn. I notice several things.
Your medium seems wet. Rooting cuttings should not be watered. I may spot a bit of rot at the bottom of picture # 1.
In any case what I would do at this stage is take it out of the pot it is in, and replace the soil with a mixture of 50/50 soil/perlite. I personally prefer rooting in just a few inches of this mixture and don't pot the cutting up until it has good roots. But if you are intent on keeping it in those big pots, then please fill the pot all the way, since the reflected heat from the sides of the pot can cause sunburn.
Good luck!
