Avocado Leaf Tip Burn and White Flaking: Root Stress or Pests

Avocado shows chronic brown leaf tips, shedding, new growth with brown spots. Leaf undersides have white flaky material along veins.

Root/Soil Dysfunction Primary

Widespread tip burn = moisture fluctuation (wet/dry cycles) or nutrient imbalance. Not a primary foliar disease.

Fuzzy photo—could be insect residue (scale, mealybug) or mineral deposit. Take leaves to nursery for hand-lens exam.

Environmental stress (water/nutrients) + possible secondary pests. Not a systemic disease. Correct cultural conditions first.
