Zinc Deficiency In Marijuana Plants

Zinc is necessary the proper growth and overall health of your marijuana plant. Zinc affects the strength of all parts of the plant such as the stems, branches, stalks and leaves. It is also a necessary element in many enzymes and a certain growth hormone called, auxin.

When plants don’t have the right amount of auxin the leaves and shoots will not grow. Zinc is also a major player in producing chlorophyll.

These deficiencies are similar to manganese and iron deficiencies, accept that they influence new growth, causing them to become motionless. Zinc deficiency happens sometimes and usually is a result of the leaf blades becoming knotted and tangled. The buds can also get tangled as well.

Signs of a zinc deficiency

Chlorosis as well as the old and new leaves turning yellow between the veins are sign of a zinc deficiency. The newer leaves will begin turning yellow between the veins. The tips of the leaves will have distorted colors and begin to die.

The plant will no longer grow upward. As a result there is not as much space between the newer nodes and this will make the new leaves get tangled. If it is producing buds the flowers will begin to die.
