TREAT A MAGNESIUM DEFICIENCY WITH A SAFE, NATURAL HOME REMEDY
Epsom salts are a natural, inexpensive and environmentally-friendly supplement for your organic Cannabis
Epsom salts (also known as hydrated magnesium sulfate, MgSO4 + 7H2O) have been used for centuries to treat human ailments, as well as providing a reliable, traditional tool for gardeners experiencing magnesium deficiencies. The salts were discovered imbuing the spring waters of Epsom, England, and are often used by gardeners as a folk-wisdom plant remedy.
As Cannabis is indeed a plant, and plants require nutrients, one common scourge of growers is the constant necessity of purchasing, using and dispensing of gallons of nutrient solutions. Various macro- and micro-nutrients can be provided in a myriad of forms; however, these days, much more emphasis is being placed upon keeping Cannabis gardens as organic as possible. Well-maintained, clean, organic grow rooms and gardens tend to produce the best-tasting, highest quality buds, which are also safer for medical patients to consume.
Epsom salts provide both magnesium (Mg) and sulfate (SO4, an ester or salt of sulfuric acid) in a gentle form that is easy for Cannabis plants to process – one that does not build up in soil over time. This home remedy is also simple to use, inexpensive and a highly-soluble supplement for organic Cannabis growers. However, Epsom salts are usually only applied to plants that are visibly lacking in magnesium, or strains that are typically magnesium-deficient.
Why do Cannabis plants need magnesium?
Magnesium allows plants to uptake phosphorous (P), nitrogen (N) and sulfur (S) from soil. Plants that are deficient tend to show yellowing leaves, which may remain green at the leaf veins. Magnesium deficiencies cause a different yellowing effect than nitrogen shortages or spider mite damage; be certain to correctly diagnose excesses and deficiencies in your plants before adjusting your nutrients, or you may burn the plants while worsening whatever deficiency ails them.
Magnesium facilitates the creation of chlorophyll and is thus critical for photosynthesis. The element also strengthens cell walls, assisting the plant in maintaining its structure and vitality. If you notice slow growth, a slight curling of the leaves and a yellowing of the leaf color (typically beginning towards the bottom of the plant), there is a good chance that your plants are magnesium-deficient. These plant symptoms are often referred to within the growing community as ‘praying for magnesium’. Begin with small doses to test the results, which you should see in about four days.
Concerning Cannabis flowers – and potentially seeds – magnesium is essential to a healthy yield. Those growing either for or from seed should note that magnesium also plays a vital role in both seed production and germination.
Why is sulfur necessary for weed plants?
In combination with magnesium, sulfur forms a sort of ‘multi-vitamin’ for plants, allowing for increased uptake and impact of nutrients and minerals, and acting as a general prophylactic for your plants. Sulfur binds with the soil to increase the availability of nitrogen (N), phosphorous (P) and potassium (K) to the plant’s roots, thus enhancing the capability of soil and added nutrients. The plant’s production of amino acids, enzymes and vitamins are all affected by sulfur levels, making the element essential to plant growth and development.
Rarely deficient in most modern Cannabis nutrients, sulfur also assists in chlorophyll production, helping gardeners to keep their plants green, vibrant and healthy. This and the aforementioned benefits are especially important for long-life plants, such as mothers or outdoor strains with a slow finish, as sulfur helps to sustain longevity and over-all plant health while protecting against environmental stress.
Technical growers should note that reverse-osmosis (RO), ion exchange or distilled watering systems will effectively remove most sulfate from drinking water, which can easily be replaced with Epsom salts, if necessary. (Growers in areas known for ‘hard’ water will often give their plants extra magnesium.)
How to Use Epsom Salts to Supplement Soil:
Whether growing in pots or beds, Epsom salts are an effective way to supplement your soil before you have even begun growing any plants; that is, if you are not
