This problem is more common in sandy textured soils/where soil profile has couple of sandy layers 3 feet below the ground…..when I sent the samples B & Iron deficiency was reported………….even after cutting those branches new leaves may come but will remain like they r in the image (common boron deficiency symptoms) at advance stage it shows die back symptoms.
