Would someone help me identify some problems on some new growth and old growth? the problem is mostly my maples, but I seem to have it on a cherry and a pear, and a fringe tree, too. Not all of my maples have "it". My soil mix is approx 80% sifted turface, 10% turkey grit, and 10% sifted pine bark fines. I defoliated a Trident forest and approx 5% of the new leaves have dark brown drying blotches and some of the leaves are curling. I water at least once per day, in the morning; and at dusk when I get home from work if they look dry. I wonder if I am watering too much. My soil mix is very free-draining. I have sprayed neem oil three times (approx two weeks apart) during the past 2 months. Here are the pics:

First is Acer rubrum (Red Maple, first year's leaves)
