DETERMINE STRAWBERRY DISEASE BY PHOTO
In strawberries, the leaves acquire a lemon color, the border dries out. What is the plant sick with?

- From the photo I can assume that in the soil where strawberries grow, there is a shortage of some nutrients. A halo around the leaf, which discolors the jagged edges of the plates, stretching of the growing leaves, a greening vein are signs of a lack of zinc.
Chlorosis between the veins indicates a deficiency of manganese - yellowish-green or yellowish-brown spots appear on the upper leaves between the veins, the veins remain green, which gives the leaves a colorful look. Subsequently, areas of chlorine tissue die off, and spots of various shapes and colors form. Similar symptoms appear primarily on young leaves, and primarily at their base, and not at the tips, as with a lack of potassium.
With iron deficiency, the veins do not change color, remain green, but the leaf blades turn pale - turn yellow.
In addition, the marginal necrosis is clearly visible in the photo - the plant suffers from a deficiency of potassium or magnesium.
Symptoms of a lack of one nutrient element can be caused not only by the lack of the required amount of one element assimilated by plants in the soil, but also by a lack of another. How to make up the deficit?
After the harvest, feed the plantation with a complex mineral fertilizer with microelements (dosage - strictly according to the instructions). Examples of such drugs: Biomaster, Fertika, Kemira, Crystal.
