Marijuana Nitrogen Deficiency

Proper Treatment of Marijuana Nitrogen Deficiency

Many aficionados could attest to the fun and pleasure experienced when growing marijuana. Nevertheless, it cannot be denied too that this venture can also involve a cautious balancing gesture making sure that you give enough to your plants. If by any chance your plant experience nutrient deficiency, it can skeptically influence the development of the plant and eventually die.

Cultivators should always manage marijuana nitrogen deficiency to prevent the unfortunate result of cannabis development. Nitrogen is known to be an essential nutrient of the marijuana plant. If your plant fails to get enough supply of nitrogen, it will begin to manifest indications of nitrogen deficiency. Apparently, the insufficiency of nitrogen is the most common.

Indications of Nitrogen Deficiency

So, how do you know if your plant is suffering from nitrogen deficiency? You will notice this condition by monitoring the lower part leaves during vegetation and early flowering period. The leaves become noticeably yellow. It is then important that you immediately do the necessary treatment if you find this condition occurring in your plant.

Nevertheless, it is also good to note that it is only typical for the huge plants to drop several leaves. However, if the marijuana plant is dropping a huge part of yellow leaves, and the said yellowing condition quickly spreads upward, you should know that you have a serious problem to deal with.

Nitrogen plays a vital part in the development and formation of buds. Compared to the other nutrients, nitrogen has the most crucial involvement in buds development. The leaves become little, less development, and the marijuana plants are likely not prospering if there is nitrogen deficiency. The stems and petioles will likely become a purple or red shade.

Excessive nitrogen provides your plant a massive, dark-green appearance. However, this makes it more vulnerable to bugs and disease. Another indication is that the stalk starts to be impoverished of stretchiness and becoming dainty.

It will be smart to know that it is typical for the marijuana leaves to become yellow during the end part of the flowering period when marijuana is getting insufficient nitrogen since it is developing buds. If you observe that your plant is quickly losing the leaves in the lower part due to the yellowing, specifically during the vegetation period, you have an on-hand problem that needs immediate treatment.

Common indications of nitrogen deficiency are the following:

  • Yellow leaves
  • Pale-colored leaves
  • Yellowing between the veins
  • Older growth and lower leaves are damaged
  • Sagging/withering

How to Treat Marijuana Nitrogen Deficiency?

For you to effectively manage and treat the nitrogen deficiency on your marijuana plant, you will have to learn the different treatments on each development stage, namely the vegetative period, early flowering period, and end of the flowering period.

Nitrogen Deficiency while in the Vegetative Period

During the period of vegetation, the marijuana absorbs as much nitrogen as it can, utilizing it to form new chunks of the plant. It goes to say that as the marijuana plant grows, its requirement for nitrogen also increases. If it does not get sufficient supply from the medium, it will begin to shove off the nitrogen from the lower parts that commonly get minimal light, to re-consume it in the development of the higher parts.

It is certainly not good to have nitrogen concerns; however, you can easily treat it. All you have to do is intensify the volume of nutrients on your next schedule of mix and you will notice the widening of the symptoms slowly stop.

Nitrogen Deficiency while in the Early Flowering Period

Once your marijuana plant has completed the vegetation period, sometime during the period, it will normally lower the penetration of nitrogen from the medium. Because of this, issues on nitrogen become a bit more crucial since you can lose a big volume of leaf mass.

To treat this problem, you can spray the plant with a nitrogen/water mix for around fifteen minutes before night-time. Relying on where you are particularly at in the flowering period, your marijuana plant may penetrate the nitrogen employing its leaves. However, you should be cautious. If you perform this, see to it that it is not a lengthened-release solution.

Nitrogen Deficiency during End of the Flowering Period

On the last 2/3 weeks during the flowering period, while you are drenching your marijuana plants, you will want this deficiency to manifest. This only implies that there is no need to worry when you observe any indication of nitrogen deficiency during the later part of the flowering period.

If you do not let this happen, the buds will not exhibit a delicious taste, may glisten a bit but will accumulate more weight. When we talk about quality, you can say that you are losing significantly. A limited quantity of nitrogen is recommended during this stage.

Common Reasons for Nitrogen Deficiency

There are two reasons why there is marijuana nitrogen deficiency:

  1. The marijuana plant is not acquiring sufficient nitrogen. There are more possibilities this will happen while in the vegetative period when the marijuana plant needs more volume of nitrogen over any other kind of nutrients.
  1. There is an incorrect pH level in the soil. When this occurs, the marijuana plant does not penetrate the nitrogen it has been granted, regardless if it has been supplied enough.


It is important that you quickly identify the occurrence of marijuana nitrogen deficiency in your plants. As a grower, you want to arrive with an outcome that is rich in yield and quality, so make sure that your plants get the necessary nutrients it needs.

Bear in mind that if you have already supplied your marijuana plant nutrients, then it is more likely that it will not suffer from nitrogen deficiency. If you notice some indications of nitrogen deficiency widening after 1 or 2 weeks of supplying it nitrogen, then you have to identify what is triggering the yellowing. If the yellowing condition happens when the harvest period is approaching, then you do not have to be worried about the yellowing since this is normal.
