The reason is that the space is closed, the photosynthesis is poor, the nutrients are insufficient, or the plants are unevenly distributed and can not get nutrients to rot. It may also be a lack of elements, phosphorus, potassium, calcium. Prevention, calcium fertilizer can be used during flowering, and calcium fertilizer should be replenished continuously at seedling stage. It is best not to plant too densely.

The incidence of low temperature is serious, and the sowing time can be delayed. Spray with 700x solution of 75% chlorothalonil wettable powder or 1500 times solution of 50% carbendazim wettable powder. Once a week, twice in a row.
