Using epsom salts in your cannabis garden

Perhaps surprising to some, epsom salts can play a key role in a cannabis garden in ensuring, that plants' nutritional needs are met and staving off nutrient deficiencies, that can damage your plants or at least rob them of reaching their full potential in terms of an abundant and quality harvest.

Epsom salts are a name given to the substance magnesium sulphate, meaning it can provide your cannabis plants with two substances vital for optimal health, which are, you guessed it, magnesium and sulphur. For this reason Epsom salts are especially useful when cannabis plants start to develop a deficiency in these nutrients.

First, let's take a look at how to apply Epsom salts in your weed garden when they are needed. Then let's explore the benefits the magnesium and sulphur, that Epsoms salts provide, and what deficiencies look like.

APPLYING EPSOM SALTS

Adding Epsom salts to your plants' soil is easy. One way to do this is to add one teaspoon of Epsom salts to 4 liters of water, which can be used as a spray or placed into your plants' water reservoir. Epsom salts can also be mixed with soil prior to planting to bolster the soil with magnesium and sulphur.

WHY YOUR WEED CROP NEEDS MAGNESIUM

Magnesium is essential in the process of photosynthesis, and without it the green pigment chlorophyll in the leaves of your cannabis plants won’t be capable of absorbing energy from the sun, which is then converted into glucose which fuels your plants survival.

Magnesium is also an essential nutrients required by plants, because it creates stabilisation in the cell membrane. The nutrient will also need to be present in the soil from early on, as it contributes to seed germination.

MAGNESIUM DEFICIENCY

Magnesium deficiency has multiple appearances in cannabis plants. This includes the edges of leaves turning yellow or a brighter shade of green, or brown spots, that develop along the edges of leaves.

WHY PLANTS NEED SULPHUR

Sulphur is another important nutrient, that plays a role in the formation of chlorophyll and therefore contributes to the process of photosynthesis. Plants will also utilise sulphur to produce vital proteins and vitamins. Sulphur also helps to defend diseases.

SULPHUR DEFICIENCY

A sulphur deficiency can be identified when leaves start to turn yellow, accompanied by the possibility of buds dying off.
