Also a question about the leaves on a Trident Maple

Hi all,

I wanted to also follow-up on a concern I have about the leaves on my Trident Maple.  I am in partial sun (zone 6), watering every day, and have fertilized.  The leaves are turning a funny color - at the least the ones toward the top of the tree.  I"m attaching a pic, and would greatly appreciate knowing if there is a problem and how to remedy it.

Thanks in advance,

looks fine to me, it is late summer and leaves will start to die off, perfectly normal.
