Older leaves become yellow between the veins if there is a loss of Magnesium.

Mottled brown spots between the veins of the leaves are a sign of Manganese deficiency.

  • Nitrogen Deficiency

Nitrogen deficiency leads the leaves on the lower side turn yellow and begin to fall off.

  • Nitrogen Toxicity

Leaves become excessively dark green, and their tips turn down. This is also known as the claw.

  • Nutrient Burn

  • Phosphorous Deficiency

  • Male Plants

Remove all plants that have both female flowers and a pollen sac to prevent pollination. These will often decrease the quality of CBD hemp oil produced after harvest. Any plants with bananas growing on the buds are male plants. During the time of stress, these bananas or stamens will also appear directly on a female plant. These produce pollen and do not even need to be open to make seeds. You, therefore, need to ensure you remove them immediately they begin growing. You will distinguish a male and a female plant by looking at whether the plant has produced any buds.
