At the risk of answering every question tonight.....where is the staff these days?.....I think your Acer is probably too exposed to the sun or wind.
Down here, not far from the coast, acers are little tricky to grow. However, I have positioned my acers.....2 of the Japanese varieties.....with taller plants to the sunny side. In one spot I have a 9' tall golden yew, a miscanthus grass and a tall agastache to create a dappled shade position for a purple Acer. Despite the strong sun, etc it's leaves are unmarked and perfect. In another spot an Acer is in shady corner with yellow philadelphus adding some protection. I think the answer is to create some plant screening Norma
