While marijuana plants don’t need a large amount of sulfur, it is still considered an essential macro element. As well as aiding enzyme formation, it helps to construct proteins. Sulfur is also pivotal in the development of chlorophyll molecules. If your plant is deficient in sulfur, calcium, magnesium, or iron, it can display symptoms like yellowing or dying leaves.
If a marijuana plant doesn’t receive enough of a nutrient, it will show signs of a deficiency. Let’s explore this issue in greater detail below.
If you allow a phosphorus deficiency to run amok, the effects are potentially devastating. Your plants will experience stunted growth, poor yields, and low resin production when they become mature. Make sure you use a fertilizer with a high amount of phosphorus or a bloom fertilizer.
There are countless nutrient options when it comes to growing cannabis. Therefore, it can be difficult for inexperienced growers to find the best choice for their plants. Arguably the biggest mistake new growers make is to turn this process into an overly complicated task. Ultimately, they spend significantly more time, effort, and cash than necessary.
Crucial Cannabis Nutrients and Deficiency Symptoms
Calcium and magnesium are often overlooked when discussing the growth of the cannabis plant. It is common to find them together in a single Cal-Mag supplement, which generally contains iron as well. These nutrients are essential to the process of photosynthesis, which involves creating energy from light. Magnesium is particularly crucial for photosynthesis; it is the central atom in the chlorophyll molecule.
Provided by air and rain, Oxygen (O), hydrogen (H), and carbon (C) are sometimes excluded in discussions of essential nutrients. This is because they are not elements that are often lacking, despite being needed in large amounts. They are also not ones that are components of any fertilizer or commercially-available nutrient package.

What follows is not an exhaustive list, but a sampling of some of the roles of micronutrients and how they aid in the development of cannabis plants:
Cannabis has thousands of unique properties, but like any other plant, it requires the same essential nutrients to properly grow and produce the desired yield of buds. Plants need relatively large amounts of macronutrients, lesser amounts of secondary nutrients, and small to trace amounts of micronutrients to germinate, grow, flower, and produce seed. All told, there are about 20 essential nutrients needed for optimal cannabis growth and development.
