In the case of improper use, drought and abnormal high temperature, sometimes slight phytotoxicity occurs because the slow-growing leaves turn yellow. The soil should be watered in time. But it will return to normal in about 1 week! You can also spray foliar fertilizers in time, such as Jieduling, Jiedu+Detoxification Agent, Yuntaishu and Gibberellin 920, and add 50 grams of urea/watering can for rapid rooting, once every 7 days, and detoxify twice continuously. Can restore normal growth, and will never affect the yield and yield.
