Recognize hemp overfertilization - signs & causes

In the world of hemp cultivation, healthy plant growth is crucial, and proper fertilization plays a central role. However, it can be easy to overdo it with fertilizer and damage your plants. In this blog post, we'll explain what hemp overfertilization is, how to recognize hemp overfertilization, and what the causes and remedies are.

If you grow in one of our Bonsanto Mini Growboxes, you are in luck! With us, overfertilization is very unlikely, because if you combine our grow boxes with the Bonsanto grow accessories such as the "Premium soil" and the "Organic Boost“ kombinierst, sind die Komponenten so aufeinander abgestimmt, dass eine Überdüngung unwahrscheinlich ist. Dies gilt selbst, wenn du Anfänger im Bereich Chili Grow bist. Halte dich einfach an unsere Bonsanto Anbauanleitung (diese findest du here) and nothing will stand in the way of healthy plant growth and a successful harvest.

What is hemp overfertilization?

Hanf Überdüngung auch Nährstoffbrand genannt beschreibt den Zustand in dem deine Hanfpflanze zu viele Nährstoffe meist in Form von Düngemitteln erhält. Chili hat zwar einen hohen Bedarf an Nährstoffen, der für das Wachstum und die Entwicklung der Pflanze wichtig ist, dennoch können zu viele Nährstoffe auch schaden. Zudem lässt sich ein Nährstoffbrand nur schwer wieder beheben.

Wenn diese Nährstoffe in zu großen Mengen zugeführt werden, können sie die Fähigkeit deiner Chili -Pflanze, Wasser aufzunehmen und andere lebenswichtige Funktionen auszuführen, beeinträchtigen. Daher solltest du darauf achten, deine Pflanze nicht zu überdüngen. Wie das Düngen funktioniert und wie viele Nährstoffe Chili -Pflanzen benötigen, erklären wir dir in einem anderen Blogbeitrag zum Thema „Fertilize hemp for a high yield harvest“.

How to recognize hemp overfertilization?

There are several signs and symptoms by which you can recognize hemp overfertilization.

Leaves

If your plant suffers from nutrient burn, this can manifest itself in yellowed leaves and yellow spots on the sides and tips of the leaves. Yellowing usually occurs when your cannabis suffers from too much nitrogen. Brown spots or dropping leaves can also be indications of overfertilization. If the leaves of your marijuana plant are deformed and curly, you must also consider a nutrient burn.

Roots

Auch die Wurzeln der Chili pflanze können dir zeigen, ob du es mit dem Dünger übertrieben hast. Wurzeln, die sehr dunkel, schlaff und faulig aussehen, sind in den meisten Fällen ein Hinweis auf Überdüngung.

Growth

If you want to investigate whether your cannabis plant is suffering from nutrient burn, you can observe the growth. If your plant grows slowly or not at all, this can be an indication of overfertilization.

Plant comparison

If you happen to grow several cannabis plants at the same time, compare the appearance and growth of the affected plants with those that were not overfertilized. If you can see a big difference, you know that the affected plants were overfertilized.

Exclusion of other symptoms

Keep in mind that some symptoms similar to overfertilization may also be caused by other stressors such as disease, pests or environmental conditions.

What are the causes of hemp overfertilization?

Over-fertilization in cannabis plants can be caused by a number of factors, often including the over-application of fertilizers. A common reason for this is that some growers are not sufficiently informed about proper fertilization methods or believe that the more fertilizer, the faster and better the plant will grow. In addition, using too high a concentration of water-soluble fertilizers can quickly lead to a buildup of nutrients in the soil, which can be harmful to plants.

Another problem is that your hemp plants need different amounts of nutrients at different stages of growth. More information on this can be found in our article "Fertilizing hemp for a bountiful harvest". Ignoring the needs of your plants and applying fertilizer without regard to growth stage can also lead to nutrient burn.

Many growers also make the mistake of fertilizing even though the soil already has enough nutrients. Without knowing the existing nutrient content in the grow medium, it is therefore difficult to find the right amount of fertilizer.

Water also often contains a high concentration of nutrients. If you ignore the nutrient content in the water when irrigating and use additional fertilizers, this can lead to an excessive accumulation of nutrients.

Klimatische Bedingungen sind ebenfalls ein wichtiger Faktor. In bestimmten Klimazonen oder bei bestimmten Wetterbedingungen kann die Fähigkeit deiner Chili Pflanze, Nährstoffe aufzunehmen, beeinträchtigt sein. Eine Düngung, die unter diesen Umständen nicht angepasst wird, kann zur Ansammlung von Nährstoffen im Boden führen, was deiner Pflanze schadet.

How to fix nutrient fire?

If you have detected overfertilization in your hemp, it is important to act quickly and fix the nutrient burn.

Stop fertilizing first to prevent further damage. This will give your plant time to recover from the over fertilization. Then start watering your cannabis with clean and pH neutral water. If your growing medium has good drainage, you can flush excess nutrients out of the soil.

The parts of your plant that are burned or where the overfertilization is visible should be removed. If you notice that your cannabis plant is slowly recovering, you can reintroduce fertilization. Nevertheless, from now on you should use a reduced dose and always keep an eye on the reaction of your plant.

In addition, also see if the environmental conditions of the hemp are appropriate and light, temperature and humidity are adjusted optimally.

Wie Chili Überdüngung vermeiden?

Of course, it is best if overfertilization does not occur in the first place. Because the Bonsanto grow components are perfectly matched to each other, you minimize the risk of overfertilization when growing in a Bonsanto Growbox considerably if you follow the growing guide . Therefore, we would recommend you to use a Bonsanto grow box for indoor growing of hemp. The Bonsanto fertilizer "Organic Boost" is beginner friendly and avoids nutrient burn.

Of course, there are other things you can consider to prevent your plant from suffering from nutrient burn.

Informieren dich über die spezifischen Nährstoffbedürfnisse von Chili -Pflanzen in ihren verschiedenen Wachstumsphasen. So weißt du, wie viel Nährstoff deine Pflanzen wann benötigen. Auch die Verwendung des richtigen Düngers ist essentiell, um eine Überdüngung zu vermeiden. Der Dünger sollte speziell für Hanfpflanzen hergestellt sein und die Nährstoffe enthalten, die dein Chili braucht. Orientiere dich beim Düngen auch immer an den Herstelleranweisungen bezüglich der Dosierung. Bist du Anfänger im Bereich des Growings, empfehlen wir dir einen organic fertilizer , because it releases the nutrients slowly and so the risk of overfertilization is relatively small.

Check the appearance of your plant regularly and watch for signs of overfertilization. This way you can determine if your plant is healthy, adjust the dosage in time and intervene if your cannabis suffers from nutrient burn.

If you do not have a Bonsanto grow box, you should perform soil tests at regular intervals to check the nutrient content in the soil. This way you can see if fertilization is necessary or not. The way you water your plant can also affect the nutrients in the soil. Excessive watering will wash all the nutrients out of the soil, while too little water will cause nutrients to collect in the soil.
