Troubleshooting Twisted Stem and Discolored Leaves in Autoflowering PlantsUpdated a month ago
If your autoflowering plant has a twisted main stem and discolored leaves, it may be experiencing stress from environmental factors. Here are some common causes and solutions:
1. Check pH and Nutrients
- pH Imbalance: Hydroponic systems require a pH of 5.5–6.5 for proper nutrient absorption.
- Nutrient Deficiency or Toxicity: Overfeeding or underfeeding can cause leaf discoloration. Use a balanced nutrient mix designed for hydroponic cannabis.
2. Ensure Proper Water and Oxygen Levels
- Roots need adequate oxygen to prevent issues like root rot. Use an air pump or ensure proper water circulation.
3. Adjust Lighting and Temperature
- Excessive heat or intense light can stress plants. Keep temperatures between 68–78°F (20–26°C) and ensure lights are not too close.
4. Strengthen the Stem
- If the stem is weak, gentle airflow from a fan can help strengthen it. You can also provide light support using soft ties.
By optimizing these factors, your plant should recover and continue growing healthily.
