Suddenly my individual Banana leaf stalks are coming away from the main stalk. I haven't seen this before and can't find it online everywhere. There are two leaves doing this thus far. I also notice the leaves seem to be closing in (see pics) I have had this for 2 years, since it was just two tiny leaves and its been growing great. Any ideas if this is normal? Is there something possibly wrong? Hopefully I added the pictures correctly, I'm new. Thank you for any insight.
