Plants detect overfertilization

Fertilization is an important issue when growing indoors. Proper fertilization allows your favorite plants to thrive better and provide higher yields. Nevertheless, it is important not to overfertilize the plants. In this blog article, we take a closer look at over-fertilization: explaining what it means, how to identify it, as well as the causes behind it and possible corrective actions.

If you use our Bonsanto Mini Growbox for your cultivation, you are on the safe side! If you use our growbox together with the Bonsanto growing accessories like the "Premium soil" and the "Organic Boost" overfertilization is very unlikely. Just follow our Bonsanto growing guide, and nothing will stand in the way of strong plant growth and a successful harvest.

What is overfertilization?

Overfertilization, also known as nutrient burn, happens when your plant gets too many nutrients mostly from fertilizers. Too many nutrients will harm your plant, so it's important to be careful not to overfertilize your plants. 

What are the signs of nutrient fire?

To detect overfertilization, look for yellow or brown leaves, especially around the edges and tips of the leaves. If the leaves look funny and curl, or if the roots are dark and limp, that can also be a sign. Over-fertilized plants also tend to grow more slowly. Also be aware that some signs may also represent disease or other problems.

What are the causes of overfertilization?

Overfertilization in plants usually comes from using too much fertilizer. Many growers don't know how to fertilize properly or think more fertilizer equals better growth. Nevertheless, the nutrient needs of plants depend on the different growth phases. 

Also, if you fertilize without knowing how many nutrients are already in the soil or water, it can cause problems. In addition, climate and weather can affect how plants absorb nutrients. Therefore, you should always adjust the fertilizer to the growing conditions.

How to fix a nutrient fire?

If you notice that your favorite plant is suffering from overfertilization, it's crucial to act quickly and fix the nutrient burn. First, you should stop fertilizing to prevent further damage. This will give your plant a chance to recover from the overfertilization. Next, you should water your hemp with clean and pH-neutral water. If your growing medium has good drainage, you can use it to flush excess nutrients out of the soil.

Remove the burned parts of your plant or the areas where the overfertilization is visible. If you notice that your favorite plant is slowly recovering, you can start fertilizing again. However, you should use a reduced dose from now on and always keep an eye on your plant's reaction.

Also check that the environmental conditions are appropriate for your plant and that light, temperature and humidity are optimally adjusted.

How to avoid overfertilization?

Ideally, overfertilization does not occur in the first place. Due to the perfect coordination of the Bonsanto Grow components, you minimize the risk of overfertilization considerably if you follow the cultivation instructions. Therefore, we recommend for indoor cultivation the use of a Bonsanto Growbox.

To prevent overfertilization, consider the specific nutrient needs of your plants at different stages of growth. Find out the right time and amount of nutrients needed. Use a fertilizer made specifically for your favorite plants that contains all the nutrients you need. Always follow the manufacturer's dosing instructions. As a beginner grower, it is recommended to use an organic fertilizer as it releases nutrients slowly and reduces the risk of over-fertilization.

Regularly monitor the appearance of your plant to detect signs of overfertilization. Adjust the dosage in time and intervene if your cannabis plant suffers from nutrient burn.

If you are not using a Bonsanto grow box, perform regular soil tests to check the nutrient content in the soil. This will help you determine if fertilization is needed or not.
