There are two reasons:
Reason 1: It could be due to insufficient micronutrients, resulting in symptoms of micronutrient deficiency on the edges of the new leaves.
Reason 2: Symptoms of nutrient deficiency on the new leaves, exacerbated by frequent spraying, may accelerate the growth of new leaves under pressure, leading to accelerated symptom development.
Here are some suggestions for adjustment:
- Increase the amount of micronutrients slightly, or adjust the EC upwards by about 0.05-0.1ms/cm or 50-100µs/cm.
- Mr Ganick Lepid 007 Concentrate + Mr Ganick Cuka Kayu Concentrate do not need to be sprayed so frequently. If there are no pests, spraying once a week should suffice. If spraying every four days is desired, the amount sprayed can be reduced by 25%-30%.
