The more experienced growers here may help more than me but here goes. I have had the same thing happen when potting pups and it may be what's called resetting?? Recently I started using a different fertilizer and the problem seems to have resolved in a couple weeks. The stems are growing taller and the leaves stopped stacking up. I can see deep green coming back in the leaves. The new fert. that is working so well is a 4 month time release called Classicote 15-8-23. A friend also put some on a banana that was not growing well and a week later a whole new leaf had come out. Keep in mind what your weather will be in 4 months if you use it, you don't want too much fert. in the soil come winter. I see you are in zone 9b, I am also in 9b with blazing heat and all my plants that can be covered have shade cloth over them.
