Tropicals & Tender Perennials: Leaf problem, 1 by TomH3787

I have four plumerias - two large plants and two that are small, rooted cuttings. The large ones and one of the cuttings are doing well. But one of the cuttings has been slow to grow and has some discolored/deformed leaves. I am tempted to trash this plant in case it has some disease that might infect the others. Attached is an image of three of the leaves. Top two pictures show a couple of the deformed leaves and the bottom shows a normal leaf. I have not sprayed this plant with anything nor has it been exposed to extreme conditions. Does anyone know if this leaf problem is temporary (maybe caused by insects or mites or the weather or a nutrient problem) or does it look serious? If there is any doubt I'm getting rid of it.
