Ask-a-Dave's-Gardener: Is My Avocado Tree Healthy, 1 by boybles

2 years ago, our mature avocado tree yielded a very good harvest. This year has been abysmal. Part of the problem may be lack of watering (we didn't notice that the sprinklers near the tree weren't working for several weeks). Now I'm afraid my gardener may be over-compensating. He fertilized the tree...and we're giving it plenty of water. But the leaves are not looking as healthy as they were last month. What do these spots mean and is the tree looking ok? Or is it typical for the leaves to start changing this way? Please let me know what you think.
