Common Cannabis Growth Challenges and Their Solutions

Below are a few other typical problems that growers may face during different stages of marijuana growth, along with their causes and potential remedies:

Hindered Growth in the Vegetative Stage

Hindered growth during the vegetative stage can result from various factors, including nutrient deficiencies, over or under-watering, extreme temperatures, and inadequate light. To tackle this issue, adjust and maintain proper nutrient levels, ensure appropriate watering and drainage, keep the temperature within the optimal range (70-85°F), and provide sufficient lighting.

Leaf Yellowing in the Vegetative Stage

Leaf yellowing during the vegetative stage may be caused by nutrient deficiencies (e.g., nitrogen, magnesium), overwatering, pH imbalances, or root damage. To address this issue, fine-tune nutrient levels, maintain proper watering and drainage, monitor pH levels, and examine roots for any signs of damage.

Stretching during the Early Flowering Stage

Stretching during the early flowering stage can be caused by insufficient light, genetics, high temperatures, or overfeeding. To solve this problem, adjust the lighting to provide more intensity or duration, choose strains that are less prone to stretching, maintain optimal temperature range, and reduce nutrient levels.

Bud Rot during Late Flowering Stage

Bud rot during the late flowering stage can be caused by high humidity, poor air circulation, or damp conditions. To solve this problem, maintain optimal humidity levels (below 50% during flowering), provide good air circulation, avoid overwatering, and inspect buds regularly for signs of rot and remove affected areas.

Preventing Nutrient Burn in the Flowering Stage

Nutrient burn during the flowering stage can result from excessive nutrient levels (e.g., nitrogen, phosphorus, potassium) or improper pH levels. To address this issue, lower nutrient levels, adjust pH levels, and flush the plant with plain water to remove excess nutrients.

Tackling Hermaphroditism

Hermaphroditism may be caused by genetics or environmental stressors. To handle this problem, eliminate any male plants that develop female flowers, maintain optimal growing conditions to minimize stress on plants, and avoid overfeeding or underfeeding your plants.

Leaf Curling during Vegetative Stage

Cause: Overwatering, underwatering, low humidity, high temperatures.

Solution: Adjust watering schedule and drainage, maintain optimal humidity levels, reduce temperature levels.

Leaf curling is a common problem during the vegetative stage of marijuana growth, and it can be caused by several factors. Overwatering or underwatering your plants can lead to leaf curling, as can low humidity levels or high temperatures. To solve this problem, adjust your watering schedule and drainage to ensure that your plants are receiving the right amount of water. Also, maintain optimal humidity levels and reduce temperature levels to prevent leaf curling from occurring.

Nutrient Lockout during Vegetative or Flowering Stage

Cause: Imbalanced pH levels, nutrient imbalances, salt buildup.

Solution: Check and adjust pH levels, flush the plant with plain water to remove salt buildup, adjust nutrient levels.

The nutrient lockout can occur when your marijuana plants are unable to absorb the nutrients they need to grow and thrive. This can happen due to imbalanced pH levels, nutrient imbalances, or salt buildup in the soil. To solve this problem, check and adjust pH levels to ensure that your plants can absorb nutrients effectively.
