An iron deficiency is first visible at the top of the plant. Young leaves look as if they have been bleached. The leaves turn yellow, while the veins remain green. This is because iron is an immobile element. What this means is that iron, when fixated, can no longer be distributed in the plant. Eventually, yellowing also occurs in the older leaves and smaller veins. In severe cases, the leaves may even die off.
Always make sure your plants can absorb enough iron. Therefore, ensure the soil has been drained properly. Symptoms of iron deficiency are most common on soils that contain a lot of calcium and have a pH value that is too high. Use one of our basic nutrients (like Terra Grow and Terra Bloom) to reduce the likelihood of an iron deficiency. Also keep abiotic factors in mind. These include temperature, light intensity, acidity, amount of moisture and wind strength.
To prevent an iron deficiency, you can use Vita Race. This is an iron spray for the growth phase and the first three weeks of the flowering phase. Other options are increasing the soil temperature and improving drainage. Is the EC or pH value too high? Then rinse your system with clean, pH-controlled water.
Iron is important for the growth and development of a plant. It is used by the plant for the formation of chlorophyll. In turn, chlorophyll plays an important role during photosynthesis. With photosynthesis, a plant creates sugars and provides itself with energy. Many enzymes also require iron to fulfil their function.
