Nutrient deficiencies and excesses in Cannabis

The massive use of fertilisers on extensive crops over the last decades is leaving a pollution footprint, both in the soil and in the atmosphere, that is now beginning to be looked at with concern. While it is well known from numerous studies that the overuse of fertilisers (especially mineral fertilisers) damages the substrate for future crops, often - even if it works against them - growers only have one thing in mind: maximising yields in their fields and facilities.

However, it is not just about how we use these products, but also about how the fertilisers are manufactured, processed and transported. Because, as in many other areas and sectors, each and every one of these steps causes pollution. It's a curious paradox... shouldn't we growers be the first to take care of the environment where we intend to plant?

Cannabis needs a good number of macro and micronutrients to be able to develop without any kind of nutritional limitation. Nitrogen, phosphorus and potassium (NPK) are probably the best known, present in most cannabis fertiliser formulas for both the vegetative or growth phase and the flowering phase, along with others such as iron, sulphur, boron and molybdenum, to mention just a few.

However, there is one very special element for the development of plants, and one that until a few years ago did not receive the attention it deserves. We are talking about silicon (Si), a nutrient that, although it is not necessary for the plant to grow and bear fruit properly, will greatly increase its defences against sources of stress such as pests, diseases or drought, while reinforcing the cell walls of plant tissues, strengthening their structure and favouring processes such as photosynthesis. Today we will talk about this interesting nutrient, see how to use it and examine its main characteristics.

Autoflowering cannabis plants are great for several reasons. They have fast growth cycles (generally less than 11 weeks from seed), they do not depend on light schedules to trigger flowering, they have a high resistance to mould and pests... but, above all, due to their short life cycle and size, autos don't require large inputs of nutritional resources, meaning that growers can save money as they won't need to feed plants for as long to get great results.

Aside from their rapid development, autoflowers have a strong and resilient nature, so they aren't too fussy about the quality of the medium they grow in and can still do well with minimal nutrients.

We receive many queries about the parameters included in the descriptions of the different cannabis strains, and more specifically, the traits section. While some aspects, like production per square meter or cannabinoid content, are very clear for the experienced grower, newcomers to the wonderful world of marijuana home growing can find them confusing.

Today, we are explaining in detail each of the attributes that can be found in the information provided by the cannabis seed banks concerning the genetics they sell. This will help you to clear any doubts when checking the strains' index cards and descriptions and to understand every trait of the plants outlined in their catalogs.

It's inevitable that at some point, almost all cannabis cultivators will find themselves in the position of needing to apply a foliar spray of one kind or another to their plants. There are many potential reasons for this: you could be in need of a fungicide or an insecticide; or maybe you want to fertilise, correct a nutrient deficiency or just give lacklustre plants a bit of a boost.

Whatever the motive for spraying, we think it's worth doing the job properly, and there are some basic measures we should take every time to make sure we get the best possible results and avoid damaging our plants. We'll deal with these ten fundamental points first, then go on to talk in a bit more depth about foliar application afterwards.

Nutrient imbalance in marijuana plants?

In this post, we will focus on the macro and micro-nutrients necessary for the development of cannabis plants. These elements are available in the nutrients, so the chosen type of fertilizer and its correct use will lead us to a crop without deficiencies or excesses, thanks to properly planned and balanced feeding.

Different factors must be considered, so we'll try to explain them simply so that all growers can dispel any doubts they may have about the nutrition of their cannabis plants.
