Epsom Salts for Cannabis
Epsom salts are crystallised magnesium sulfate, a naturally occurring mineral essential for all living organisms. Magnesium sulfate is found in 95% of mineral waters and constitutes up to 2% of ocean seawater.
Many foods are low in this mineral, leading to widespread deficiencies. Increasing magnesium sulfate intake can help reduce severe asthma attacks and control seizures associated with toxaemia during pregnancy. It is beneficial for various muscle contraction issues and certain cardiac rhythm disorders. For centuries, Epsom salts have been utilised as a liver cleanser and laxative.
When used as a bath salt, magnesium sulfate can be absorbed through the skin, helping to draw out toxins, sedate the nervous system, reduce swelling, and relax muscles. Epsom salts are named after the mineral-rich waters of Epsom, England, where they were originally produced by evaporating spring water.
How Do Epsom Salts Help Cannabis Plants?
Epsom salts provide two essential elements that plants require: magnesium and sulfur, which become available in a soluble form that can be absorbed through both leaves and roots. At the appropriate dilution, Epsom salts are also beneficial to soil health and stimulate microbial life.
As with any substance, overuse can harm the soil and plants. Balance is key; if your plants do not need Epsom salts, it's best not to use them. A large outdoor plant grown in well-cultivated soil with a balanced nutrient supply will typically not display any signs of magnesium deficiency.
Indoor plants grown in containers, however, often have limited root systems, making them more susceptible to nutrient deficiencies. Magnesium deficiency in cannabis first appears on the lower leaves, with the green tissue between the veins beginning to lighten. As the deficiency worsens, the leaves will start to yellow.
Dosing
- Use 1 dessert tablespoon of Epsom salts per 5 litres of water.
- Dissolve the Epsom salts in hot water to ensure complete dissolution.
Application:
1. As a foliar spray: Mist generously after the lights turn off. Repeat every three days until you see improvement.
2. When watering: Use once during the vegetative stage and twice during flowering (on day 10 and day 35).
Epsom salts should only be used if you observe signs of magnesium deficiency.
