Good afternoon Jeff,
Thank you for your question! It looks like you have a sucking insect, maybe thrips, or it could be another sucking insect. There also may be a fungus on the edge. I’d recommend emailing the MSU Plant and Pest Dagnostic lab for confirmation with pictures, including one of the whole plant, and any plant history- how they water, what chemicals they applied. You can reach them @ <personal data hidden>.

Thank you for your question.
Good luck & have a great day!
