How to Prevent Nitrogen, Calcium & Magnesium by Nebula Haze |
Cannabis plants grow best when they're getting the nutrients they need at the right time. Humans are the same way; if we're missing certain vitamins it limits our growth when we're young, and as we get older a lack of vitamins causes us to become sick in strange ways. Conversely, humans can also run into problems when they get an overabundance of vitamins.

Just like humans with vitamins, giving cannabis too high levels of nutrients can also cause problems. Like many things in life, cannabis plants (and plants in general) need a sort of
balance.
Luckily, for the most part, cannabis plants are not too picky about nutrients despite what nutrient companies might have you believe.
Cannabis is generally not that picky about nutrients, except for a few...
Your cannabis plants can tolerate a wide range of environments, but there are a few nutrients which tend to cause problems more often than others. If these nutrients aren’t present in the correct amounts, it will affect your growth rates, as well as the quality and quantity of your buds.
Most nutrient deficiencies are caused by the wrong root pH, but sometimes you actually need to add more or less of a particular nutrient for plants to grow their best.
A few major nutrients often cause problems that are not related to pH. Although pH can be the culprit, these nutrients often need to be provided in higher or lower doses to prevent
deficiencies/toxicities.
Many growers need more or less of these nutrients for proper cannabis growth and bud formation:
Nitrogen (N)
First, there’s nitrogen…Nitrogen makes up more of your plant (as a percentage of dry mass) than pretty much any other nutrient or mineral, and it plays a hand in many plant processes.
Without an external source of nitrogen, your plant cannot grow past its first or second set of leaves.
Nitrogen is that important to growth and photosynthesis.
With nitrogen, you can get both deficiencies and toxicities.
Here's what to look out for...
Symptoms of Nitrogen
Deficiency
- Lower growth on the plant turns yellow and sometimes the yellow leaves get brown splotches.
- Affected leaves become soft and start wilting.
- Once the leaf has wilted, it sometimes dries up and turns crispy.
- Leaves fall off the plant on their own; a gentle tug will remove affected leaves.
- If left unchecked, a nitrogen deficiency will climb up the plant.
- There are other nutrient problems that cause the lower leaves of a cannabis plant to turn
yellow, but only a nitrogen deficiency causes leaves to become soft enough to fall off on their own.
It is normal to lose a few leaves to nitrogen deficiencies here and there, especially if you have a lot of lower leaves that are receiving low amounts of light. It's also normal to see nitrogen deficiencies in the second half of the flowering stage as the plants are focusing on buds instead of
leaves.
However, if you see a nitrogen deficiency early in the plant's life, or if you're losing tons of leaves at once, a nitrogen deficiency needs to be addressed immediately.
But it's not just too little nitrogen that causes problems. Often, you'll see problems caused by too much nitrogen; a nitrogen toxicity.
Symptoms of Nitrogen Toxicity
- Leaves can become dark green and sometimes shiny looking
- Tips of leaves are bent sharply down in what's known as "the
Claw."
- Buds grow slowly and final taste/smell is not as good as normal.
Leaf tips pointing down from nitrogen toxicity Here's what a nitrogen toxicity looks like during flowering. This much nitrogen during the budding stage will cause buds to develop more slowly and reduce overall yields. Plus,
nitrogen-burnt buds tend to carry a "hay" or "fresh-cut grass" taste/smell even after being harvested and cured. Many new growers accidentally give their plants too much Nitrogen, especially in the flowering stage
As a grower, you're interested in how much nitrogen to give your plants at a specific time. The ratio of nitrogen to other nutrients has a huge effect on growth and bud formation.
Vegetative Stage - higher levels of nitrogen (pretty much any plant food will do)
Most complete plant foods that you get at a gardening store contain high levels of nitrogen (N). These nutrient systems tend to work well in the vegetative stage.
Some examples of cannabis-friendly one-part Vegetative nutrient systems...
- Dyna-Gro “Foliage Pro”
- General Hydroponics “FloraNova Grow”
- Pretty much any complete plant food
Flowering Stage - lower levels of Nitrogen (use "Bloom" or Cactus nutrients)
It’s extra important to find a nutrient system with lower levels of nitrogen for the last part of your plant’s life. Many “Bloom” or "Flowering" style base nutrients are just the ticket.
Some examples of good one-part Flowering nutrient systems...
- Dyna-Gro “Bloom”
- General Hydroponics “FloraNova Bloom”
- If you can’t order online and can't find a good one-part base Bloom formula locally, you do have other choices. Though not an ideal choice, most Cactus plant foods will contain good nutrient ratios for growing cannabis during the budding stage. So in a pinch, you can use the cactus nutrients that can be found at most gardening stores.
Okay, now that you’ve got a handle on
nitrogen….

Trophy Picture of the Week! |
"This is a black cream autoflower by sweetseeds pretty close to harvest. This phenotype grew like a sativa kinda with long internodal spacing and has a sativa buzz that moves into a nice body high. Good medical strain for sure. Oh and it is sweet and creamy tasting and smooth as hell."

I'll be honest with you, when I first started growing, I struggled. Now, it is my mission to
make it easier for new growers to get started as well as help advanced growers get bigger, better yields with less time and money. We are updating and adding articles every single week and our goal is to eventually build a comprehensive growing resource so anyone and everyone can grow if they want to! If we all share the knowledge there's more buds in the world for everyone :) |

Sirius Fourside is a hobbyist grower who has gained the bulk of his experience growing in water as a medium (deep water culture, bubbleponics).
"Growing cannabis can be a relaxing hobby in and of itself, but it also saves you money and keeps you from having to deal with shady characters. Cannabis is much easier to grow than people give it credit for, and growing in water
doesn't increase the difficulty much, if any. But whether you want to grow in water, coco, or a different medium, we'll show you how easy it can be!"
