The period of vegetative growth itself can be divided into two main phases:
I. Rooting
The first stage is related to the rooting of the grafted plants. It lasts 10-14 days. If grown outside and in colder weather it may take a little longer.
For this stage, we recommend feeding with a liquid fertilizer containing ammonium acids and trace elements, or a liquid fertilizer with a high phosphorus content can also be applied. Applying an optimal amount of phosphorus ensures strong root development, optimal stem growth, flower formation, and an increase in the number of seeds.
Consumption rate:
MGP Amino - 10 ml /1 liter working solution
MGP UNIVERSAL – 200–300 ml/10 l of water
II. Vegetative growth
During this period the plant almost reaches its final growth. In the beginning, the growth is slow, but then the growth intensifies, and in general, 5 - 12 pairs of leaves are formed during this period. Cannabis is a plant that during its development needs large amounts of nitrogen, especially during this period. With a good nitrogen supply, the plants will grow quickly and become large and healthy.
For this period, we recommend combined nutrition - alternating foliar and fertigation.
Foliar:
MGP NPSMg 20 – 30 ml /1 liter of water
Fertigation:
MGP NPSMg - 30 – 50 ml/liter of water
Cannabis needs large amounts of phosphorus, especially during seed germination and ripening. The vegetative phase usually ends in the third to fifth month. This way of feeding continues until the pre-flowering phase.
