How To Recognize Magnesium Deficiencies In Marijuana Plants

A lack of magnesium (Mg) can occur in all planting mediums and hydroponic systems. It does not often happen to outdoor marijuana growers however. Symptoms will start in the lower leaves, as they begin to yellow and exhibit chlorosis. These leaves will start to curl inward and eventually die. Edges of the leaves feel dry and crunchy to the touch. The deficiency will work itself up toward the middle and upper section of the leaves. The growing shoots will eventually shift from a pale green to a white color. The stems and petioles will all start to turn purple. This ability to travel upward makes a magnesium deficiency very mobile.

Magnesium’s main goal is to promote healthy veins and spur on the production of leaves. It is also needed for the production of chlorophyll and the breaking down of enzymes. Download my free marijuana grow bible for more tips about nutrients and marijuana plant deficiencies.

To fix a magnesium deficiency, there are a number of solutions, but the best one may be the use of a product called Marijuana Booster. It’s something that many growers use to improve the quality of their yields, but it will also ensure a healthy balance of nutrients.

Other fixes include:

  • Magnesium sulfate
  • Epsom salts
  • Dolomite lime
  • Garden lime
  • Worm castings

Magnesium sulfate and Epsom salts work the fastest because they are water soluble. Indeed, Epsom salts are the easiest fix for hydroponic systems. Use a teaspoon of Epsom salts per every gallon of water in the tank. Treat with a quarter of the original dosage for each subsequent treatment. You can also employ the use of Calcium-Magnesium.
