Hello everyone, I've got a very small orchard of about 30 heirloom apple trees on mm.111 planted about ten months ago. The trees seemed to be doing fairly well until yesterday I noticed a good amount of leaves were turning brown on a couple of trees. I'm pretty inexperienced but the pattern of browning looked like fire blight. I was wondering if you guys could take a look at a few pics and tell me what you think.

From what I've read, fire blight manifests itself in the Spring. I don't believe that either of these trees had any blossoms this past spring. Weather has been hot ~100 for the past month or so with hardly any rain (7b). The trees are irrigated with drip tape. Thanks in advance for your help.
