This JJ Tinkerbell has had crinkled leaves almost all season and only recently started yellowing. I hung sticky cards and there were hardly any pests and no leafhoppers. The leaves haven't been falling and the plant is always very full, but it definitely isn't healthy. Any help is appreciated.

Check the bottom of the leaves for spider mites. They're very tiny but do have some webbing too. The only time I've had leaves like that on mine, I did have spider mites.

I agree with Karen.

Thank you. I'll inspect them closer first thing in the morning.
