Plant Deficiencies

There are a lot of things that can go wrong while growing marijuana plants. One issue that regularly occurs is that a deficiency happens where the marijuana plant will need something replaced in order to keep it living healthily. There are a lot of signs for this and solutions as well.

Nitrogen Deficiency

If the bigger leaves change to yellow in color but the smaller leaves stay green then that is a sign that the marijuana plant is going through a nitrogen deficiency. If this happens then you should mix in some organic fertilizer or nitrate of soda.

Phosphorus Deficiency

If the aged marijuana leaves start to curl around the edge and change to a darker color then that is a sign of a phosphorus deficiency. If this happens then you should throw in some commercial phosphate to solve the problem.

Magnesium Deficiency

If the marijuana leaves that reached maturity level have started to show a bit of yellow coloring to the veins then this is a sign of a magnesium deficiency. To solve this you will have to mix in some commercial fertilizer which contains magnesium.

Potassium Deficiency

If the matured marijuana leaves change color to yellow and the edges of the leaves turn to a darker shade of gray then there is a good chance that the plant has a potassium deficiency. Just give the weed plant some muriate of potash to solve this problem.

Boron Deficiency


If the stems of the weed plant crack then that is a sign of a boron deficiency. Just give the marijuana plant some plant food which contains some boron and this will be solved.

Zinc Deficiency

If the marijuana leaves are small and wrinkled and the veins are a shade of yellow then there is a zinc deficiency. Just give the weed plant some plant food that contains zinc and it will be fine.

Molybdenum deficiency

If the younger marijuana leaves start to get deformed and possibly change to a shade of yellow in color then it’s likely a molybdenum deficiency. Just give the weed plant some plant food that contains some molybdenum and it should be alright.
