response: Hi Steve - Thanks for including those photos.  I see that you have a red maple (aka swamp maple).  Your tree has chlorosis, that is why the leaves look yellowish with prominent green veins.  So I have several suggestions for you.    First, you should have your soil tested to check the pH level.  Then, have a leaf tested to see if it has manganese or iron deficiency.  Correct these deficiencies (to find a certified arborist: https://www.asm-isa.org/content.aspx?page_id=22&club_id=883139&module_id=274045)  Lastly, be sure to clean up all the fallen leaves, in case your leaf spots are caused by a fungal disease.  Here are some support links:  https://www.canr.msu.edu/resources/chlorosis and https://www.canr.msu.edu/news/why_do_my_maple_leaves_have_spots Also, this is how to get soil and foliar tests:  https://homesoiltest.msu.edu/get-started/ (tests are available at your Oakland County extension office)   https://www.canr.msu.edu/pestid/submit-samples/  The problem you can't correct is that this tree is placed on the side of a hill.  This means that the irrigation water and rain water will drain more quickly than on a flat surface.   I hope this helps you!
