When moving this plant from inside a packed terrarium of many tangled plants to my greenhouse two weeks ago, I accidentally knocked 1" off the tip of the growth point from my N. x 'Momoka'... It is insignisx merrilliana but the grower who sold it to my grew it in my conditions, highland intermediate. I got it in April and it grew well from then until now. After I broke the tip off of the growth point, it stopped growing. You can see a little divider in the growth tip -- what is that? I was thinking it might be the new leaf and the next growth tip, so I may have broken two. Why would it have stopped growing? Temperatures have been the same now as they were when I got it. What could be wrong? What can I do to help fix it?
