I got two plants that look unhappy. I don't know what it is. I don't see any insects or any other signs that there might be any. They were healthy when I bought them. I got them from a local nursery but I also have others from the same place and they are fine. I find it odd that its only these two plants which are the same variety. Its some hybrid, I think, called "sweet heat". I got them to please the few in the family who don't like a lot of heat. They continue to grow but all the new growth looks all wrinkled and curled. Any ideas what might be wrong?
