I got this bougie from @aml1014 awhile back when he had his moving sale. I haven't done anything to it besides watering and fertilizing. It is growing, but the new leaves are different than the mature leaves. They are kind of ruffled. I've inspected the plant, and can't find any evidence of insects. I tapped the branches over white paper, no black spots. It seems to be thriving, but I am concerned about the unusual new growth. Any ideas?
