3 Simple Ways To Spot Deficiency In Cannabis Plants

Cannabis---Garden

Cannabis cultivation may be a two-edged blade. On the one hand, it has the potential to be one of the most significant, meaningful, and rewarding experiences of your life. Many of the frequent cannabis plant inadequacies, on the other hand, may make cultivating cannabis one of the most irritating activities you will ever do.

It’s practically hard not to get emotionally attached to a cannabis garden. This is equally true in terms of monetary investment. So, when anything goes wrong in a lawn, no matter how big or little the project is, it can be devastating.

But how to figure out if your cannabis plant has some deficiency? Read on to know some of the most frequent issues you may detect by looking at the leaves and helping them give a speedy recovery.

How to check for cannabis deficiency?

While it can be tough to ascertain cannabis deficiencies, here are some of the most frequent growth issues and how they may be identified on cannabis leaves:

Nitrogen deficiency:

The most prevalent shortfall identified by cannabis farmers is nitrogen insufficiency. Although it bears a fundamental similarity to numerous other problems in the early stages, it’s typically straightforward to recognize, and you can remedy it as soon as it gets noticeable.

In the early phases of nitrogen shortage, the leaves seem to be overly pale in color—almost yellowish-green—compared to the healthy leaves’ deep green. Nitrogen-deficient leaves also exhibit somewhat darker veins than the relatively pale color of the leaf tissue itself, albeit the difference is not as pronounced as in specific other deficits.

On the other hand, nitrogen poisoning causes leaves to become an extremely dark green color that may seem practically black under challenging situations. When there is a significant nitrogen deficit, the leaves become lighter in color and finally dry up and die. The more giant leaves on the plant’s lower and outer sections are frequently the first to be damaged and perish.

How to treat it?

It is not necessary to remedy nitrogen deficiency if it is discovered in the latter stages of blooming. In reality, since the older leaves are no longer required, it’s normal for them to fall off and die at this stage.

However, since it impacts the plant’s capacity to photosynthesize energy, a nitrogen shortfall in vegetative development may significantly influence total production and quality. Nitrogen insufficiency is usually rectified by simply improving the strength of your regular NPK-based diet, but if finer tuning is necessary, nitrogen-only additions are readily available.

Phosphorus deficiency:

Phosphorus deficiency is uncommon, but you should take it seriously. It may produce lower growth rates, tiny leaves, weak foundations, and seedlings that are generally deficient in vigor if it impacts plants in the vegetative growth stage. Phosphorus deficit causes leaves to look dark yet washed-out, with black veins and lighter leaf tissue in the early stages.

Purplish discolorations emerge on the main section of the leaves as time goes on, and the leaf margins become dark and curl downwards. The leaf twigs (the short stalk that connects the leaf to the primary stem) may also start to turn purple. Large portions of the leaflets become purplish-brown and die later, while the remaining parts turn mottled yellowish-green.

Again, phosphorus deficiency generally manifests itself first in the outer, lower leaves. Unlike nitrogen deficit, however, phosphorus deprivation is problematic since the plants need high amounts of phosphorus during the blooming phase.

How to treat it?

You may remedy a phosphorus deficit in several ways. Just keep in mind to take it slowly. If any cure is overused, the plant may not acquire enough other nutrients and suffer. As a result, performing poorer than if it had been left undisturbed. Keeping that in mind, here are three options for resolving the issue:

  • Temperature: Keep the temperature above 15 degrees Celsius since cooler temperatures make phosphorus absorption harder for cannabis plants.
  • Watering: Make sure the plants are adequately watered. Phosphorus insufficiency may be caused by too much water and compacted soil.
  • pH products: To ensure the grounds have the proper pH, use a pH boost or pH down solution. It should be in the range of 6 to 7.

Potassium deficiency:

Yellowish leaflets with darker lines and crusty, brown leaf margins and tips indicate a potassium deficiency. Potassium deficits are uncommon in hydroponics, although they are more prevalent when cultivating in the soil or a planting media. Potassium shortages are common when your selected medium contains too much nitrogen or calcium, making it difficult to fix with combined-nutrient diets.

The margins of the lower outer leaves become light yellow in the initial phases of potassium shortage, but the veins stay green. The tops and margins of the leaves may become dry and brown, curling up or down.

How to treat it?

Getting a potassium deficit treated as soon as possible is critical for developing terpenes, which alter the flavor and scent of your marijuana. To begin, check the pH of the soil since too high pH is perhaps the most prevalent cause of potassium shortage.

Cannabis plants will find it challenging to absorb potassium in soil with a high pH. The pH level should be from 6 to 7. However, it should be somewhat more acidic in hydro systems. In such instances, strive for a score of 5.5–6.5. And, as usual, enough irrigation is critical.

In conclusion

While the symptoms of the deficiencies given above may seem identical, keeping a careful eye on your plants from the start can help you recognize them immediately. If you realize anything is out of the ordinary, remain stable and follow these instructions to choose the best course of action.
