Usually red spider mites or other sucking pests are present at this growth stage, spray with an insecticide like Abamectin or Spiromesifen. Approximately five days after spraying the insecticide, apply a foliar fertilizer containing essential micronutrients such as Calcium (Ca), Boron (B), Zinc (Zn), and Manganese (Mn). Or fish amino acid is good to spray.
