Carol check the underside of the leaves with a magnifying glass for spider mites. In your second picture I see tiny dots on the stem and the leaf but I can't tell if it may be potting soil or mites.
The leaf curl could be a calcium deficiency but I'm just guessing here as there are a couple of deficiencys that look very similar.
I had a leaf curl problem a couple of years ago and some added gypsum took care of the problem.
Hopefully Monika will come along with her trained eye.
Here's a picture of a leaf with calcium deficiency so you can compare it to yours. Notice the leaf edges are curled under.
Do you know what the PH of your soil is?
