What does the flowering of a Marijuana Plant consist of?

During the flowering weeks, the cannabis plant sticks its final lug and develops its buds. All a visual spectacle that should be accompanied with certain care, depending on the variety, Indica or Sativa, and the stage of development in which the plant is. Nutrients, daylight hours, times. We offer you the definitive guide to get the most out of this important final period. Then all that remains is to reap the sticky results of a job well done.

Our plants have already germinated. they have grown for a few weeks taking shape and preparing for the greatest metamorphosis of their short life: flowering. Here the plants begin to change their appearance. developing pistils, doubling or quadrupling their size and forming resinous buds. All this explosion of nature implies that the rules of the game have changed, the plant has other needs and requires other types of care.

Therefore, the cannabiculturist must be sensible and interpret the factors that must be altered during this period in order for the plant to develop its full potential. These requirements do not change at once, so we must keep an eye on the calendar and accompany the flowering stage week after week. with what best suits our cannabis plant.

Pre-flowering phase

The plants have grown in the previous weeks in a healthy and attractive way and it is time to prepare them for the change. This phase is a transitional stage between growth and flowering. In fact, during these first 2-3 weeks we will not see a glimpse of the flowers, but we will witness a rapid and unprecedented growth of the plant.

To start this stretch the first thing we have to do is change the photoperiod. If until now we were growing indoors and using timers to recreate periods of 18/6 hours, with enough light for the plants in their growth stage, now we will balance the photoperiod to 12/12. which will help us induce the plants to flowering. It is here when the plants stick the lug until flowering, a process whose rhythm is determined by genetics, that is, the stretching of an Indica plant and that of a Sativa have nothing to do.

This is determined by the origin of provenance of the varieties. While Sativas come from tropical places with many hours of daylight, Indicas come from colder regions with fewer hours of daily sunlight. The more hours of sun, the greater the growth, and the fewer, the faster the flowering. In other words, Sativas will grow much higher and buds will take longer to develop, while Indicas will grow less with a faster flowering.

This fact is quite important when making an ‘indoor’ space for our plants, since when flowering approaches, they will give an important stretch. The  Sativas pure can reach quadrupling its initial size at this stage. For this reason, some cannabis growers decide to put a 12/12 photoperiod from when the plant germinates, to control its height and that it does not exceed the available interior space. The Indicas. on the other hand, usually only double their size in the pre-flowering, which indicates that this phase also lasts less than in the Sativas, that is, they start flowering earlier.

Flowering: times and nutrients

When the plants have finished stretching, they change the chip and focus all their energy on bud development. From the second week on we will start to see the first white pistils that will attest that the flowering has started. This also indicates that nutritional needs are going to be different, and that phosphorus and potassium are going to take on a greater role than the hitherto most present nitrogen. Even so, as we have been warning, the rhythms will depend largely on genetics.

Varieties Sativas have a slower flowering period. so they require lower levels of nutrients and a progressive rise week after week. Indicas, on the other hand, having a faster flowering phase. usually need more nutrients and concentrate in a few weeks, since they have less time than Sativas to develop their buds well. However, most strains today are hybrids  This should serve as a reference depending on which of the two varieties predominates, although it is best to mix the two nutritional regimes.

The basis of the diet during this stage will be based on five nutrients: nitrogen, phosphorous, potassium, calcium and magnesium. The first to be used, and the most essential in all flowering, will be nitrogen. In stretching, before the plant has entered flowering, the plant will need high doses of nitrogen (always somewhat less Sativa than Indicas). Nitrogen will help the plant to finish developing its robust plant structure and then support the weight of the buds. If the leaves turn yellow, the plant will be announcing that it suffers from a lack of nitrogen; it is important to remedy soon.

In the third and fourth week of flowering we will have reached the peak of nitrogen, and we must reduce the amount in favor of phosphorus and potassium, two nutrients of which we will increase the presence. From the third week of flowering we will also include calcium. We can even add it before, especially if the plant has small white spots that end up being holes, since this indicates that the plant suffers from calcium deficiencies.
