With the leaves dying from the outer edges like those shown,the condition could be Leaf Scorch.Was the weather particularly harsh and hot?

September had a few days with mid 90s and two weeks in the mid 80s.
Too much fertilizer could cause that scorching too. One should not be fertilizing this time of year. I stop after august 1st. It is probably climate though.
Thanks vrk for posting on my behalf and thanks for the responses. Been watering it twice a week. Last fertilized mid july. This year the plant got less sun compared to last year. That makes it even more strange. Does alkaline ph cause this? I checked and it’s pretty alkaline. Will try adding some soil acidifiers and vinegar.any other suggestions to improve the situation?
