In this article we will discuss:
Sulfur deficiencies in marijuana plants are quite rare. This is a good thing because good growing roots, the proper amount of chlorophyll, and the development of plant proteins are all processes aided by sulfur throughout the vegetation stage.
Signs of a sulfur deficiency
When the leaves begin to slim and get fragile, the plants growth will slow down. In contrast, the leaves will also be smaller. When in the flowering stage the buds begin to die off and the whole plants growth may slow down.
If the issue is serious, the veins of the plant may become yellow and the damaging parts will most likely show up at the bottom of the leaf. The slim, woody stems will continue growing taller but will not expand.

Having too much sulfur will reduce the size of your plant and cause the leaves to look dead and brown on the tips. Too much sulfur has the same damaging effect as salt with reduced growth and dark colors.

How to fix a sulfur deficiency
The simplest way to cure a sulfur deficiency is by using Epsom salts (wiki). All you have to do is water the plant with Epsom salts and wait until it gets better. Use one, maybe two teaspoons of Epsom salts per gallon of water. If you have any other nutrients that have sulfur in it, feel free to add that as well. A good water-soluble fertilizer that contains sulfur will work just fine.
Here are some other choices:
- Elemental garden sulfur
- Potassium sulfate
Never put gypsum on soil that has a pH lower than 5.5. It can create an environment that is toxic to the plants.
Another excellent product you can use is Marijuana Booster. This will offer the perfect mix of nutrients to provide the greatest yields.
Last but not least, check and fix your pH levels to ensure the sulfur isn’t getting blocked out. Sulfur travels at a slow pace throughout the plant so it could be a few days once the issue is resolved before you will see that things are getting better for your plant.
