Why are my marijuana leaves curling up in Word?

Curling marijuana leaves can indicate several issues, including nutrient deficiencies, overwatering, underwatering, or environmental stress. If leaves are curling upwards, it may suggest too much light or heat, while downward curling can indicate overwatering or root problems. To diagnose the issue, check the plant's watering schedule, light intensity, and nutrient levels. Adjusting these factors can help restore the leaves to a healthy state.
