b'Lack of magnesiumExcess symptomsAn excess of magnesium does not immediately lead to symptoms. It can be stated that an excess of magnesium leads to deficiencies of calcium and potassium.SodiumSodium is considered as mineral that the plant does not need. The strawberry plant is very sensitive to sodium. Excess symptomsAs the sodium content increases, the overall plant development is less and the leaf margins can burn. Salinization can cause growth problems in field grown crops. Due to high concentrations in the soil moisture, the plant can hardly absorb water and at the same time the loss of water from the leaves accelerates due evaporation. The plant absorbs a lot of sodium, which is toxic in the plant and therefore absorbs less potassium, which causes a lack of potassium in the plant.114'
