And we're at the next part of our fertilizer series, which is coming to its sixth sequel. Over the past 6 months, we have gone through all the basic divisions of fertilizers, their division and use, and now we are slowly continuing with additives or supplements that can help us to the best harvest.
As for additives, we already have, for example, root stimulators, enzymes, flushes, and recently we have also discussed flowering enhancers quite widely. This time we will focus on the lesser known, but still very effective and beneficial helpers for every good grower.
It's been a long time since I've first heard about growers supplying silicon to plants. At that time, there was only one liquid preparation based on silicon and in a minimal concentration, so I did not attach much weight to it, but people around me saw the change at first glance. Only in the last few years have I fully understood what they meant. And since then, without silicon-based products, I really couldn't imagine quality cultivation. It has so many benefits!
Silicon is, as many know, a building block. An element that the world cannot do without. It is contained in soil, glass, but of course also in humans and plants. And how does it work?
If we were to imagine silicon visually, we could imagine it as an elevator. An elevator that goes up and down in a large department store and on each of the many floors will drop off one of its passengers. This passenger then goes to his favorite store, from where he will never get, and thus strengthens the functioning of the entire shopping center.
Silicon behaves in the same way - it is deposited in the cell walls of the plant and significantly strengthens it, which is reflected in the enormous growth of the stem and its significant strengthening. For this reason, many growers have also stopped using support nets and various support rods - due to the strength of the stem, this is simply sometimes not even necessary. And as every more experienced grower knows - the stronger the stem, the bigger the flower!
But the story of silicon and the elevator does not end there. Silicon, just as well as it delivers itself, can help other elements to places where they are needed. This is due to the fact that a cavity is created inside the stem, which improves the metabolism of the plant and delivers the basic elements where it has it, in a faster course.
Strengthening the cell walls also results in greater resistance of plants to fungi and pests. Therefore, thick cell walls are visible not only on the stems, but also on the leaves, which are thicker and more powerful.
As for the application of silicon-based supplements, it is possible both in the form of grout and in the form of spraying - I recommend combining both of these forms to achieve the best possible result! When spraying, however, always give a maximum of half the dosage.
One more important thing needs to be said - silicon reacts with other elements, so it is always necessary to add it to the water first, mix it properly and then add other components. Otherwise, it may react with other elements and your nutrient solution may turn milky white. If this happens, pour out the solution and mix the nutrient solution again. Otherwise, it can be said that it is an immediate aid for the formation of strong stems and very material sticks!
CalMag is a combination of two elements, namely calcium (calcium) and magnesium (magnesium). It is no coincidence that these two elements are available as a whole, as the more extensive calcium is again a reactive element with other macro elements such as potassium and phosphorus. It is also possible to buy calcium in small quantities with nitrogen, but calcium and magnesium themselves are a great supplement that needs nothing more if you add it to your basic fertilizers.
Calcium is an immobile element that is responsible for the growth of cell membranes and ensures the proper flow of sugars. While magnesium is a building block in the foliage area - it is the basis for the development of chlorophyll, which, as we already know, helps the process of photosynthesis. Together, these two ingredients are a great addition to any cultivation method, be it soil, coconut, hydro or aero.
Sometimes these components are literally indispensable, especially when we use rainwater to water or refill the tank. Unlike tap water or water from an osmotic unit, it does not contain any calcium at all - which is unacceptable for cannabis plants. For this reason, it must be supplemented externally.
There can also be a problem in some big cities - water purifiers sometimes use descaling filters, so they can deprive us of precious calcium.
Calcium deficiency is manifested by yellow dots on the leaves, which over time spread to yellow spots with golden edges and twisted leaf tips. This deficit is manifesting itself very quickly, so it needs to be addressed immediately.
It is recommended that CalMag be added to the diet at least once a week. In acute cases, it can also be applied by spraying on the leaf - calcium is more easily absorbed.
