Celery question

[gardenvt]

I don't think anyone answered SLC about the celery. I have the same thing going on and wondered what it could be.

I have 2 celery plants where the leaves suddenly started looking odd - like the photo SLC posted - the celery stalks look fine.

Anyone know what this might be?

Are these the celery pictures you are talking about?

gardenvt, I believe that's what you are referring to?
