My trees are well established and really big. My middle tree clearly is struggling. The leaves are small barely blooming but the problem is the tips are getting soft and squishy. The surrounding trees have no problem. First pic you can tell leaves are not full, second pic is tree next to it which if full and blooming. Any thoughts or ideas. Not sure if it's fungus? Can't be dehydrated since plants next to it are ok? Want to save it!! Help!! Anyone seen this?
