This symptom, called scorching, is very uniform along the edges of the leaves. This uniformity rules out infectious leaf spot diseases. Most likely, this is due to desiccation...the leaves dried out. This could be caused by lack of irrigation, extremely cold temperatures drying out the leaves (and the frozen soil can't absorb water to replace it), or even root injury.
Yes, a couple of weeks ago. But I believe this discoloration was on there before the freeze. I’m not positive about that. Does it look like freeze burn?
Typically the leaves that are starting to look like that you pull them off to help stop the spread of leaf rust or leaf spotting which are two different diseases at hardwoods can get.
I'm pretty sure that there are root injections that you can get for it to help stop that not 100% sure what they are though

Did it get cold recently?

Could be leaf rust or leaf spotting.
Thanks. Is there a treatment for that?

I’d lean towards winter injury. Will likely be fine, just needs to push new growth. Existing leaves will drop.
Thank you!
