| I don't see anything to be concerned about. New growths are smaller until it grows in and bulb to swells. Be patient.
As for the blackened new growth, I would remove it. Sometimes you can use a sterile knife and cut it off without having to take the whole plant out of the pot. Unless the black is going deep into the roots, then you'll have to cut the roots off too. Then sprinkle cinnamon on the cut to prevent infection. The plant will survive. Cyms. are really hard to kill.
