Troubleshooting Guide for Cannabis Growth
Identifying and solving issues at each stage of cannabis cultivation is vital for healthy plants and successful yields. Here's a overview of common problems and their solutions during each growing stage:
Common Problems
During Germination
1. Seeds Not Sprouting- Cause: Poor seed quality, incorrect temperature, or inadequate moisture.
- Solution: Use high-quality seeds, maintain a warm temperature (21-27°C or 70-80°F), and ensure consistent moisture without over-saturating.
- Cause: Excess moisture and poor airflow.
- Solution: Ensure proper ventilation and reduce moisture levels. Use sterile materials to avoid contamination.
- Cause: Improper humidity levels.
- Solution: Maintain moderate humidity and avoid overwatering.
During Seedling Stage
1. Stretching- Cause: Insufficient light.
- Solution: Increase light intensity and reduce the distance between the light and seedlings.
- Cause: Overwatering or nutrient deficiencies.
- Solution: Allow soil to dry between waterings and provide balanced nutrients suitable for seedlings.
- Cause: Underwatering, overwatering, or high temperatures.
- Solution: Monitor watering schedule and ensure the correct temperature range.
During Vegetative Stage
1. Nutrient Deficiencies- Cause: Lack of nitrogen.
- Solution: Use a vegetative-stage nutrient mix high in nitrogen.
- Cause: Excessive watering leads to drooping or slow growth.
- Solution: Let the topsoil dry out between waterings and improve drainage.
- Cause: Dense foliage creates moisture and hiding spots.
- Solution: Maintain airflow and regularly inspect and clean plants.
- Cause: Insufficient light.
- Solution: Increase light intensity or adjust light positioning.
During Pre-flowering Stage
1. Overstretching- Cause: Weak lighting or excessive nitrogen.
- Solution: Balance nutrients and increase light intensity or modify light cycle.
- Cause: Stress from light leaks or temperature fluctuations.
- Solution: Ensure a consistent light schedule and stable temperatures.
- Cause: Lack of phosphorus or potassium.
- Solution: Adjust nutrient regimen to include more phosphorus and potassium.
- Cause: Increased foliage attracts pests and holds moisture.
- Solution: Improve airflow and implement pest control measures.
During Flowering Stage
1. Bud Rot or Mold- Cause: High humidity and poor airflow.
- Solution: Lower humidity and increase air circulation.
- Cause: Overfeeding.
- Solution: Reduce nutrient concentrations and flush the medium if necessary.
- Cause: Light leaks or incorrect spectrum.
- Solution: Check for light tightness and use flowering-specific light spectrums.
- Cause: Dense buds attract pests.
- Solution: Regularly inspect for pests and use integrated pest management strategies.
During Harvesting Stage
1. Mold or Rot- Cause: High humidity.
- Solution: Harvest in a dry environment and dry plants quickly after cutting.
- Cause: Harvesting too early or late.
- Solution: Monitor trichome development and use a magnifying glass to determine harvest readiness.
- Cause: Poorly Maintained and or Dull Tools.
- Solution: Regularly sharpen and sanitize your tools.
During Drying and Curing Stage
1. Over-drying- Cause: Inadequate control of drying conditions.
- Solution: Monitor and maintain optimal humidity, temperature and airflow during drying.
- Cause: High humidity.
- Solution: Keep humidity levels low and ensure proper ventilation.
- Cause: Inadequate air circulation.
- Solution: Use fans for airflow and rotate buds for even drying.
By recognizing and addressing these common issues promptly, home growers can ensure healthy plants and achieve high-quality cannabis yields.
