I bought what was supposed to be B. arborea. The original plant died, but I managed to salvage and root 2 small cuttings. I have them on a top shelf in my orchid greenhouse. Until the last week, they were growing well. This is what the new growth looks like today. This is a photo of one of the cuttings. The leaves are malformed, thick and the tip has become a tendril. What is causing this? Should I pinch the malformed growth? Do I need to spray?
