Potted Citrus Tree Leaf Disease

For the last few days, the leaves on my potted citrus trees are looking like scorched. I have these trees for over 10 years and never have any issues with them. All of them have the same issue. Pictures are attached for identifying the problem. Any help will be appreciated. Need to save them ASAP. Thanks.

If this time in container didn't include root pruning, then it may be time to do so. That, or pot up the next size. It may be cramped up and fighting itself for room and nutrients.

To be sure, I would treat with a fungicide, and pot up if you are able to.

Thanks BushDoctor.
I did add citrus fertilizer and compost and pot-up this spring. They were all repotted last year. There were tons of flowers but they all fell down.
I used Neem oil as preventive measure. Will definitely try some fungicide.
