Buying Guide – Choosing The Best Nutrients

Just like for any other living organism, nutrients are extremely important for weed as well. An efficient hydroponics system, along with a proper glow light and an optimum amount of nutrients, is all that you need for some top quality weed.

It’s essential to understand a lot of things because cannabis is a complex plant that requires a lot of attention and an appropriate amount of nutrients at different times and stages.

The Basics

Your weed’s proper growth and health depend on three main elements.
Nitrogen (N)
Phosphorus (P)
Potassium (K)

Your weed’s growth process is divided into two main stages, and you need to provide the plant with the appropriate amount of nutrients precisely according to the stage that your plant is in.

The two stages are:

Vegetative Stage: The Roots

Mentioned below are the ratios of elements that you need to use during this stage:
Nitrogen Level – High
Phosphorus Level – Medium
Potassium Level – Medium

Now let’s look into the logic behind these ratios:

Nitrogen is the most important component of your weed growth. For fast and healthy growth, using high levels of nitrogen for your plants is the best choice, one that will give you beautifully green, buds.

Phosphorus, in this stage, is best used in medium amounts. It’s responsible for making your weed diseases resistant, making the roots and the stem strong and healthy, and enhancing the nutrient uptake of your plant.

Potassium is not required in a significant amount, but it still is very important for your plant. It’s responsible for making the stem and root tissues stronger, and it also adds volume to the buds and helps in synthesizing the amino acids, proteins, and other elements in the plant.

The ratios given above are the most favorable for your plant as nitrogen is the most essential nutrient your weed needs during the growth stage so that the buds grow out to be strong, healthy, and with great texture.

Flowering Stage: The Flowers & Buds

Following are the best ratios for your weed’s flowering stage:
Nitrogen Level – Low
Phosphorus Level – Medium
Potassium Level – High

Now let’s look into the details:

You must keep the Nitrogen levels on the low in the flowering stage because too much nitrogen in this stage will make it hard for your plan to form proper buds. Furthermore, it will decrease the overall yield and make the leaves lose their greenery.

Phosphorus in the flowering stage is quite important. What it does is that it promotes the growth of healthy, beautiful looking flowers. And it also adds a lot to the overall health of your plant and weed.

The best element in the flowering stage is Potassium. Potassium helps in the development of terpenes, which is responsible for your weed’s aroma. Moreover, it helps in flower formation and makes your buds much tastier.

What Nutrients To Buy?

The best answer to this question is ‘choose the nutrient bottle that consists of precisely what your weed needs, in that particular stage.’ We’ll elaborate on this further, now.

A high level of nitrogen, medium level of phosphorus, and a low level of potassium are what you need in the vegetative stage.

A bottle with low levels of nitrogen, medium levels of phosphorus, and a high level of potassium are what your cannabis needs, in the flowering stage.

All this leads us to the next question: Organic or Chemical Nutrients?

It might sound pretty simple and straightforward, but there is quite a few difference in both these categories that need to be addressed.

Chemical or Organic?

Let’s look into both these options separately as both of them have different and unique advantages.

Chemical Nutrients

Possibly the biggest plus point of using chemical nutrients is that it makes the growth process extremely fast. So, if you don’t like waiting around too much, chemical nutrients should be your go-to option.

Chemical nutrients also work best in a hydroponics system, and they’ll help you keep the process simple and away from being messy.

Chemical nutrients also increase potency, or so they say. So potency combined with fast growth ends up making chemical nutrients the best choice of nutrients for many growers. But then again, it ultimately boils down to the growth medium you’re using and what your objectives are.

Organic Nutrients

If you’re an all things natural type of person, then, organic nutrients are a great choice for you. They’re also the most favorable if you’re using soil for your weed’s growth.
For better aroma and taste, organic nutrients are a great option. We’re not saying that chemical nutrients cant do that, but organic nutrients give off far better results in this case, compared to the chemical ones.

Organic nutrients in a hydroponics system never sit well, as they tend to start the growth of other unwanted plants inside the system. Furthermore, organic nutrients can also make problems for the nutrient uptake cycle.

A Key Notice – Check Your Plant’s Water!
The challenging part about the growth of weed is the fact that the plant, just like any other plant, is prone to a lot of deficiencies.

In many cases, growers are faced with a situation where they’re not getting good results, and they’re facing a lot of problems even when they’re providing proper nutrients to their plants.

You might be wondering how that’s possible? We’ll summarize that in two words: Water pH
Simply put, water pH is important because it helps in your plants’ absorption capabilities, so if the water pH isn’t optimal, your plant automatically won’t be able to absorb the nutrients it is being supplied with efficiently.

Sure, the right ratios are important; what’s more important is the absorption. The right amount of pH value for your water depends on the type of medium you’re using. You’re in luck because we’ve mentioned those pH levels for you, below:

Hydroponics: The optimum water pH level for this is 5.5 to 6
Soil: The optimum water pH level for this is 6 to 7

As written above, alkaline waters are favorable for plants being grown through hydroponics. On the other hand, for soil growth, the water pH levels need to be more acidic.

As the water pH values are directly related to how much nutrients your plants will absorb, it is advised that you keep a pH tester with you, so you can keep track of the pH values and help your plant get the maximum amount of nutrients.

The Conclusion

All in all, two main questions need to be asked:

How am I going to grow my weed? In soil or the water?

What are the best nutrient ratios for my weed?

Apart from these two questions, the brand you choose for your nutrients is also important, and that is where our top 10 list will help you, as those products are guaranteed to give you results.

Ingredients are also an important component that requires consideration. Still, the products listed above are already consisting of top quality ingredients, which will surely make your plants stronger and your weed, greener.
