Is this leaf scorch on my Fuji cherry?

The leaves are turning brown and crunchy at the ends. A little info. It currently gets sun from sunrise (6am) till around 2pm, I was using a sprinkler to water it when I was away for two weeks earlier this month. I have it mostly protected from the wind, & I don't see any holes in the leave, but the second picture shows a leaf cutter or caterpillar was on it. Is this a disease or no?

Mine is an absolute water hog, colonizes the pot with roots in a single season, and typically looks ratty once the weather warms up. But I still like it. Those crispy leaves are most likely its protest of your departure.

I figured that was the reason. I sprayed it with fungicide anyways.
