In hydroponic gardening, leaf curling is often caused by insufficient light, high temperature, nutrient imbalance, or root hypoxia. To control curling, ensure the plant receives sufficient and soft light, keep the water temperature at 20-25°C, and change the nutrient solution regularly to avoid nutrient imbalance. At the same time, timely observation of the plant's condition, timely identification of the cause, and adjustment can help it resume healthy growth.
