Overwatering is a common issue faced by cannabis growers, leading to drooping plants with curled-down leaves. It can occur when plants receive excessive water or when watering frequency is too high, causing the roots to sit in stagnant water. Over time, overwatered plants may exhibit chlorosis, which is leaf yellowing resembling a nitrogen deficiency. The symptoms are especially prominent in young plants and seedlings. The roots of cannabis plants require oxygen, and overwatering restricts their access to it, resulting in the drooping appearance.

Cause of Issue
◉ Watering too frequently ◉ Growing plants in a medium with poor drainage ◉ Insufficient airflow within the growing medium
Symptoms
◉ Droopy plants with leaves curling down from the stem to the leaf. ◉ Yellowing of leaves, resembling nutrient deficiencies, especially in younger plants and seedlings. ◉ The growing medium may become thick, wet, and muddy, exacerbating the issue. ◉ Plants show signs of stunted growth and brown spots on leaves.
Corrective Actions
◉ Wait until the top inch of the growing medium is dry before watering again. ◉ Ensure that water drains easily out of the bottom of the pots. Around 20% extra runoff water should be observed. ◉ If the growing medium remains consistently wet for an extended period, consider reducing the amount of water given at a time or improving drainage. ◉ Aim to water the plants every 2-3 days, adjusting the quantity based on how quickly the medium dries out. ◉ The "lift the pot" method can also be used, where the pot feels relatively light when the plants have consumed most of the water. ◉ If the growing medium retains moisture for an extended period, leading to overwatering, better drainage is necessary. This issue can occur when small plants are placed in overly large pots. ◉ In cases of severe overwatering, increasing temperature and airflow can aid in the evaporation of excess moisture. Gentle aeration through air holes made with a pencil can also help oxygenate the roots. ◉ Please note that these suggestions should be adjusted based on your specific growing medium and environmental conditions.
