When you repotted it was it just moved up into a larger pot or were the roots disturbed at all? If there was any root loss then the top growth will tend to die back. The potting mix in its pot looks almost all the way to the top, how are you watering it? Also I wonder about drainage since the pot seems to be set into another pot that also has potting mix in it. Just wondering why have potting mix in the outer pot as well?
