    not sure what had happened to my lemon tree. Pale new leaves and some orange leaves at some area. See photos attached. This plant in grown on ground.

    And my calamasi develop similar yellow patch at some area. This plant is grow in container. I look at some resource it seems boron toxicity but not sure. Need expert here to identify and how to take care of this.

    Have you ever had your water tested for pH and mineral content? Boron toxicities to Citrus are generally attributed to coming from the water.

    Have you fertilized these trees since your post and if so what form, liquid or granular, of fertilizer did you use, how much and how often was it applied and what was the formulation?
