Last update on 2019-11-21 / Affiliate links / Images from Amazon Product Advertising API

Here we have a very simple product, not a whole kit like the others we have reviewed so far. Here you get a large bottle of flowering nutrients for your weed plants, and that is it.

However, although it does not come with a bunch of other fancy stuff, this Botanicare Pure Blend Pro Bloom does do its job quite well. Something we do like here is that this product is organic and natural, so while you still have to flush plants in the end, at least you can be sure that only organic nutrients were used.

What you need to know here is that Botanicare Pure Blend has an NPK ratio of 2-3-5, which is more than ideal for marijuana plants in their flowering stage.

This product comes with many different benefits including the fact that it helps to increase nutrient absorption and synthesis, it increases the metabolic rate of the plant, it speeds up growth, keeps roots healthy, and of course, it will help your pot plants grow really nice, large, and potent buds that will be a joy to smoke.

What is also important to note about this Botanicare Pro Bloom, is that it can be used when growing weed in soil, with a hydroponic system, or in coco coir as well. When it comes down to it, if you just want a simple flowering nutrient solution, this is a great way to go.

Now, it does not contain any nitrogen and it has an NPK ratio of 0-19-39, which means that it contains an insane amount of phosphorus and potassium, which is perfect for your weed plants.

There is a reason why it is called Bud Explosion, an it is because the high PK content helps to greatly increase and speed up bud growth during the flowering stage.

Why Are Nutrients Important During The Flowering Stage?


Just to be clear, the flowering stage of the marijuana growth cycle is all about cola and bud growth, or in other words, the growth of the marijuana flowers which you will end up drying and curing, and then smoking, vaping, turning into edibles, or extracting the THC from.

Therefore, to get the biggest, best, and most potent yields, you want to supply your weed plants with the proper nutrients, and the right amounts of them, during the flowering stage of growth.


What Is NPK? – The Main Marijuana Nutrients

NPK is actually an acronym for the 3 main nutrients which marijuana plants need for ideal growth. N stands for nitrogen, P stands for phosphorus, and K stands for potassium.

What is important to keep in mind here is that the nutrient requirements of marijuana plants during the vegetative state is different from the flowering state.

During the vegetative state, as well as the very early flowering stage, in order to spur on a lot of vegetative plant growth, you want to use nutrients with high nitrogen levels, medium phosphorus levels, and fairly high potassium levels.

However, during the flowering stage, you want to decrease nitrogen levels, slightly increase phosphorus levels, and greatly increase potassium levels.

What is important to note here is that for the flowering stage of marijuana growth, you want to ensure that you do not use nutrients that contain a lot of nitrogen, as they may actually restrict fast and big weed bud growth.

However, for this stage, both phosphorus and potassium are extremely important in order to get really big buds and to create an awesome flowering stage with tons of new growth.


What About Organic Nutrients?

One thing to note here is that when you are growing marijuana in soil, you would be wise to go with organic nutrients. This way, you know exactly what you are feeding your plants, and therefore there is nothing to worry about when you consume it.

However, beware that you should not really be using organic nutrients for hydroponic grow operations, as they may cause the growth of bacteria in the water and may mess with pH levels.


Flowering Nutrients & Sativa vs Indica

Sativa and Indica

Something else not note here is that there are of course 2 main different kinds of marijuana, these being cannabis Indica and cannabis Sativa.

What you need to know here is that cannabis Indica plants can usually handle a lot more nutrients than cannabis Sativa plants.

Simply put, cannabis Sativa plants do not require as high a level of nutrients for proper growth, which is true for both the vegetative state of growth as well as the flowering stage.

Before you begin feeding your weed plants any nutrients, it is wise to look up the nutrient requirements of the specific marijuana strain you are growing.

We have covered a detailed guide on the different strains, you can check it out here.


How To Get The Biggest Buds During Weed Flowering – Some Tips

Of course, you want the highest yield possible from your weed plants, which is why right now we are going to give you some general tips on how to get the biggest buds during the flowering stage of marijuana growth.

  • Remember that maintaining the proper pH level will allow the marijuana plant’s roots to absorb the maximum amount of nutrients possible. The wrong pH level will result in an inadequate root system that is unable to properly absorb nutrients.
  • Another great way to ensure that your pot plants engage in the proper synthesis of nutrients is to ensure that they get more than enough light.
  • Keep in mind that during the flowering stage, maintaining the proper temperature and humidity for your weed plants is also very important, and goes a long way in determining the amount of nutrients your pot plants can absorb, and how well they are put to use. Keep in mind that this also has to do with air ventilation and circulation.
  • If you want to ensure that your plants get more light, engaging in weed plant topping or training your weed plants by tying them down is also something you can do (we have covered a good guide on topping here).

ALWAYS FOLLOW THE DIRECTIONS ON THE NUTRIENT BOTTLES!

important

Something that we really cannot stress enough here is that it is very important to provide your plant with the proper amount of nutrients, but not too much. Remember guys, there is such a thing as nutrient burn, which happens when you supply your pot plants with too many nutrients.

So, for one, always remember to look at the soil you are using, if you are using soil. Most high quality potting soils for weed already contain a fair amount of nutrients, which means that feeding liquid or powder nutrients to your pot plants is not quite as important.

Moreover, be sure to always read and follow the directions on the bottle to ensure that you don’t overfeed your pot plants with so many nutrients that you end up burning them.


Conclusion

There you have it folks, more or less everything you need to know about the right nutrients to use during the flowering stage of cannabis growth. In terms of the best nutrients for flowering stage of marijuana growth, we would absolutely recommend looking into one of the products which we have reviewed above.

Remember folks, using the right nutrients and the right amounts of them will make all of the difference when it comes to maximizing the quality and quantity of your final yield.
