Canna Mono Magnesio (MgO 7%) 1L

 Furthermore, magnesium influences other pigments and physiological processes. This makes it an essential element in the development of the plant.

CANNA Magnesium can be directly absorbed by the plant and therefore the effects can be seen quite soon. It can be used as a fertiliser for magnesium deficiency and as a supplementary nutrient to stimulate the growth and bloom.

Symptoms of a deficiency

When there is a shortage, the leaf green in the medium-old leaves under the flowering top will be broken up, and the magnesium will be transported into the young parts of the plant. This breakdown is visible as rusty brown spots and/or vague, cloudy, yellow spots between the veins. A slight shortage of magnesium hardly affects flowering, although the development of the flowers makes the deficiency symptoms worse.

Development of a deficiency

• Signs of a deficiency first appear around the 4th-6th week. Small, rusty brown spots and/or cloudy yellow flecks appear in the middle-aged leaves (under the top of the plant). The colour of the young leaves and the fruit development are not affected.
• The size and number of rust-brown spots on the leaves increase.
• The symptoms spread out over the whole plant, which looks ill. When the shortage becomes acute, the younger leaves are also affected and flower production will be reduced.

Reasons for a deficiency

The magnesium deficiency can occur because uptake is inhibited because of:

• A very wet, cold and/or acidic root environment.
• A high quantity of potassium, ammonia and/or calcium (for instance high concentrations of calcium carbonate in drinking water, or clay soils rich in calcium) in comparison with the quantity of magnesium.
• A limited root system and heavy plant demands.
• A high EC in the growing medium, which hinders evaporation.
