Potassium deficiency

Potassium deficiency

Plants suffering from a lack of potassium are smaller with a short, limp stem. In addition, you can recognise the deficiency by smaller flower tops and pale fruits. Leaves can turn yellow or die off. This starts first at the edges. There can also be brown or burned spots. A potassium deficiency is initially visible at the older leaves, because potassium is mobile. The young leaves draw the potassium from the older leaves. Potassium deficiency results in a low yield with poor quality.

How do you recognise a potassium deficiency?
  • Plants are smaller and have a limp stem
  • In addition, you recognise it by smaller flower tops and pale fruit
  • Leaves may have brown spots, brown veins, yellow edges or yellowing veins
  • Plants with a potassium deficiency can absorb less water
  • Reduced yield
What is the (possible) cause?
  • Too low of a potassium content in the soil or in the substrate
  • Too high of a calcium or magnesium content in the soil or substrate
  • Incorrect fertilisation
  • Too much sodium in the root environment
How can you prevent it?
To prevent a potassium deficiency, you can use Plagron Bat Guano. This bat manure is very rich in potassium and phosphorus, which ensures extremely exuberant flowering of the plant. Potassium is best absorbed if the pH value remains between 6.0 and 7.0. By using basic nutrients like Alga Grow, Alga Bloom, Terra Grow, Terra Bloom, HydroA&B, CocosA&B, you will decrease the chance of a potassium deficiency. Please always be aware that abiotic factors like temperature, light intensity, acidity, amount of moisture and wind strength can also have a big influence on deficiencies.

How can you cure it?
To stop the potassium deficiency, Green Sensation offers a solution. Green Sensation is a liquid fertiliser that provides plants with extra phosphorus and potassium in the flowering phase. This creates more compact, harder and heavier fruits.

What does potassium do for the plant?
Potassium improves, among other things, the resistance of the plant and helps to strengthen the cell wall. It regulates the opening and closing of stomata, with which the plant regulates the absorption of carbon dioxide (CO2), water vapor and oxygen. Proper functioning of the stomata is essential for photosynthesis, transport of nutrients and cooling down of the plant. This improves the resistance of the plant, which is essential for the quality of the end product.
