To start, you need to keep in mind that cannabis plants are very particular about their environment. To successfully grow a cannabis plant, you need to understand the ideal temperature, humidity levels, amount of light, and nutrient-rich diet your plant needs to thrive.
Just like humans, plants need certain things to survive and thrive. If something is missing from your cannabis plant’s environment, these deficiencies will be reflected in the way it grows. Prolonged deficiencies can even cause stress in your plant (yup, plants get stressed, too). This stress will make it more susceptible to several growth-inhibiting factors like bugs and pests, mold, diseases, and tricky issues.
Once you learn to spot the signs and symptoms of various deficiencies, you’ll be able to remedy the situation and improve your plant’s health. Read on to learn more about common nutrient deficiencies, tips to correct existing deficiencies, and how to prevent them in the first place.

การขาดกัญชาคืออะไร?
Have you ever heard of humans having a vitamin or mineral deficiency? Well, it turns out your plants can suffer from the same thing. All living creatures require a set of nutrients that they need to function and grow the way they’re supposed to, and when something is missing, it can have a drastic effect.
When it comes to cannabis plants, these deficiencies can manifest in reduced level of THC and quantity of the cannabinoid/terpene yields. In some cases, it can even kill your cannabis plant if you don’t address the issue in time.
This information can feel a bit overwhelming the first time you learn it, but don’t be discouraged! The good news is that even though there are many things (or lack of things, to be precise), that can cause deficiencies, each type of deficiency has pretty specific symptoms that you can identify if you know what to look for.
These symptoms and signs can manifest in changes to the leaves, the overall appearance of the plant, and a few other visual signals that we’ll outline below.

Unfortunately, ensuring that your plant gets all the nutrients it needs isn’t just down to the feed you give it. You could have the most perfectly balanced, nutrient-rich food globally, but your plant could still have nutrient deficiencies. Talk about frustrating! The reason that this occurs is that the food is only part of the picture. The other thing to consider is how your plant can absorb the nutrients you’re trying to give it. To the surprise of many, nutrient absorption depends mainly on the soil’s pH level. For your cannabis plant to absorb those nutrients, the soil pH levels must fall within a given range. Soil that is too alkaline or acidic will block your plant’s roots from absorbing any nutrients.
Given that soil pH is like a nutrient gatekeeper for your cannabis plants, you should always check the pH levels before investigating other nutrient deficiencies. Even if your plant is deficient in a given nutrient, it may just be because you need to adjust the pH levels of your soil.
Ideally, the pH levels of your soil or another growing medium should fall between 5.8-and 6.8. The ideal value is right around 6.3, but if your pH falls between that range, it should be acceptable and likely isn’t preventing your roots from absorbing nutrients. Typically, the pH of your soil (or alternative) should self-regulate to fall at the correct pH, but some factors like water pH could influence it to fall outside of the desired range.
Macronutrients are nutrients that your cannabis plant needs to receive in large quantities. In the same way, humans need fat, carbs, and protein; plants need Nitrogen, Phosphorus, and Potassium, to name a few. These macronutrients are necessary for the healthy growth of the plant, and they feel the majority of the core biochemical processes that occur during development and bloom.
Micronutrients are needed in much smaller quantities— but are needed all the same. These nutrients, including silicon, Zinc, Copper, and Sulphur, help with the plant’s cellular biological function.
In addition to macro and micronutrients, your cannabis plant also has (and needs) two other types of nutrients: mobile and immobile.
As the names suggest, mobile nutrients can move throughout the plant if necessary. On the other hand, immobile nutrients are not able to move once the plant has deposited them.
When you’re facing a mobile nutrient deficiency, you will be able to spot it most easily in the old-growth of the plant. This is because the plant will prioritize the new growth and, if faced with a deficiency of a mobile nutrient, will siphon the nutrient out of an older part of the plant and into the more recent piece. Common examples of mobile nutrients are Magnesium, Phosphorous, Nitrogen, Potassium, and Nickel.
Immobile nutrient deficiencies present the opposite problem. These nutrients are tethered to certain parts of the plant, so if a nutrient deficiency occurs during new growth, that’s where you’ll notice the symptoms of an immobile nutrient deficiency (but the old-growth will look just fine). Common immobile nutrients are Manganese, Zinc, Sulfur, Boron, Calcium, Iron, Copper, and Molybdenum.

Anyone who has ever faced any problem will tell you: it is far easier to prevent a problem than to repair the damage after the fact. Sometimes this is easier said than done, however, so you must understand the signs and symptoms of each nutrient deficiency. Otherwise, you may accidentally exacerbate the problem you’re trying to fix.
We emphasize that you need to learn the ins and outs of the deficiencies because the symptoms of various cannabis deficiencies are pretty similar. To the untrained eye, it can be nearly impossible to discern the difference between a Manganese deficiency and a Zinc deficiency (both cause lightening of the leaves). Still, the treatment for each is quite different.
To combat deficiencies in a general sense, many professional growers will opt for what we sometimes call the “small fish in a big pond” solution. This method involves using larger pots of nutrient-rich soil for each plant. The cannabis plant has a much larger nutrient reserve to draw from.
Be warned, though, that this method has its drawbacks as well. Chief among them is the potential for your plant to experience a nutrient excess. Yes— not only do you need to look out for nutrient deficiencies, but you also need to look out for nutrient excesses. Check out the handy graphic for more info on how the various nutrient deficiencies or excesses can present themselves.
Additionally, it’s also possible for your cannabis plant to simultaneously suffer from multiple nutrient deficiencies. If you’re using good, professionally prepared soil, you notice symptoms of various shortcomings. However, it’s likely a sign that your soil pH is out of whack, causing nutrient lockout in your plant’s roots.
การขาดสารอาหาร – วิธีการวินิจฉัยและรักษาพวกเขา?
If you suspect you may have a nutrient deficiency problem with your cannabis plant, the best thing to do is act as quickly as possible. Catching it early can make a world of difference. Still, before you begin trying to solve the problem, you must be able to identify what the problem is correct. The minute you notice any sign or symptom that something isn’t right with your plant, you should be donning your Sherlock Holmes hat and solving the mystery of what exactly is amiss. Keep in mind that the longer you wait, the more seriously the issue will impact your yield and harvest. Always aim to keep your plants in perfect or near-perfect health because an unhealthy plant will succumb to problems far more quickly than a healthy plant.
Here are some of the most common nutrient deficiencies, their identifying symptoms, treatment methods, and how to prevent them.

อาการ
You can spot a Phosphorous deficiency by brown discoloration on the leaves or the appearance of red or purple dead spots on the stems of your leaves. Additionally (or) you may notice that the entire leaf seems to have taken on a darker hue, appearing dark blue or dark green. This nutrient deficiency can also cause leaves to curl and fall, and, like with Nitrogen, you will first notice these symptoms at the bottom of the plant.

Keeping your plants healthy is essential for maximizing their yield and ensuring that they stick around for a long time. Plants have a given set of nutrients that they need to grow and function properly, and without these nutrients, you’ll quickly begin to notice the adverse effects. You can think of these nutrients as the different parts of a car engine— the car might still run without one of the parts, but you probably won’t get very far at all.
These nutrients are crucial to helping your cannabis plant perform the physiological functions required to produce the yields you need. Unfortunately, a deficiency in even one of these nutrients can significantly impact your yield and production.
If you notice that your plants are starting to look a little worse for the wear, don’t panic. These things happen, and now that you know all about nutrient deficiencies, you’ll be able to step in and save the day. Keep in mind that in many cases, the culprit responsible will be an imbalanced soil pH. Although it seems extreme, when the soil pH isn’t in the correct range, the roots cannot absorb the nutrients they need. Even if the soil is rich in every crucial nutrient, nothing will change until the pH levels are adjusted.
When attempting to diagnose a nutrient deficiency in your cannabis plant, look very closely at all symptoms to identify the correct one. Given that nutrient excess is possible, you don’t want to accidentally give your plant too much of one nutrient rather than solving the deficiency of another nutrient.
It would help if you also kept in mind that a nutrient deficiency may not be the issue at all in some cases. Cannabis plants are sensitive to many things, and nutrient deficiencies are just a few. Make sure you’re paying close attention to how much you’re watering your plants because overwatering can cause many problems (including preventing your plant from absorbing vital nutrients). You’ll also want to make sure that the temperature of the space where you’re growing your cannabis is within an ideal range, and the same goes for the humidity. It would help if you aimed to keep the humidity of the space around 40-50% and the temperature between 68 to 77 degrees Fahrenheit.
Growing cannabis is usually quite simple, but in the beginning, it might take you a second to develop a system or method that works for you. Many new plant growers (not just cannabis growers) tend to be a bit overenthusiastic about feeding or watering their plants, which can inadvertently cause many problems to occur. Remember that these plants evolved to thrive in specific conditions, and as long as you can mimic those conditions, they should do just fine.

About a week.
Nitrogen-starved plants quickly take in the nutrient once it’s made available to them. There will be an enhancement in the plant’s color to a more vibrant green. Damaged leaves can’t grow back. Typically, plant life can bounce back in a week.
