Cannabis plants’ life cycle is divided into two periods; the growth stage and the bloom stage.
- During the growth or veg stage, cannabis plants grow in size and produce many more branches, preparing themselves to easily hold up the flowers that it’s about to start growing.
- During the flowering or bloom stage, cannabis plants spend most of their energy crating and fattening their flowers (buds).
During the flowering stage, your plants are going to need more nutrients, specifically, phosphorus and potassium. However, we highly recommend using growth fertilizers too during the first two growth weeks; your plants are still growing and need a lot more nitrogen still.
Plant nutrition during the flowering stage is reflected in the harvest. If you want a large, high quality harvest, you’ll need to pay close attention to the products used during this stage.
In order to give your plants the right nutrition, you’ll need to have a good idea of what types of products you can and can’t use, and when you need to use them.
How to Tell if Cannabis is in Flower?
The start of the flowering period is relatively easy to detect. If you’re growing outdoors, it begins at the end of summer when there’s less light. When growing indoors, you’ll know they’re going to flower as soon as you flip the lights from 18/6 to 12/12h.
Keep in mind that these rules are only specifically designed for light-dependant cannabis plants. When it comes to autoflowering seeds, they don’t need any type of specific light schedule to begin flowering; they should start from the 3rd to 4th week onwards.
However, regardless of the type of strain, there is an unmistakable sign that they’ve began to flower:
When you see little groups of 10 – 20 pistils all over the plant, it’s a sign that it’s beginning to flower and it’s time to switch nutrients.
Fertilizers for Flowering Marihuana
There are plenty of types of fertilizers for flowering cannabis, as well as lots of brands. We’re going to go through some of our best-selling fertilizers so that you can choose whichever adapts best to your needs.
At La Huerta Grow Shop you can find all types of organic flowering nutrients such as the sought-after Bio Bloom by BioBizz.
You should begin using fertilizers for the flowering period during the second week after switching the lights.
Outdoors it will depend on the stain and the hemisphere you’re in. You’ll need to keep an eye out for the first few groups of pistils before using bloom nutrients.
Before the flowering period we recommend using some sort of flowering stimulant such as Delta 9, which can be used 10 days before flipping the lights and during the entire flowering period. This stimulator is great for increasing the formation and growth of new buds as well as cannabinoid and resin yield.
The second flowering period coincides with the 3rd – 4th week of strains that take 6 weeks to flower, and from the 4th week on in strains that take 8 weeks or longer. This phase is when you can start using products designed for but fattening such as Canna PK 13 14, or the powerful Blossom Builder by Atami. You can also complement the flowering period using additives such as Bud Candy, which contains carbohydrates and natural sugars that increase the density of flowers and their aroma.
Cannabis Bloom Nutrients Recommendations
Plus, you should wash out your plants roots 10 days before harvesting. Depending on the amount of nutrients left over in your plants, they may need extra cleaners such as Canna Flush to help them along.
Outdoor Flowering Nutrients
There are various types of flowering fertilizers, and we stock some of the highest quality products out there. You simply need to know when and in which stage you should be using them. Each and every grow has its own characteristics, which is why nutrient brands manufacture various ranges for each flowering period and type of grow.
Growing in The Ground
- We recommend using powder fertilizers such as Bat Guano by Plagron or the potent Growilla Bud by Botanicare – liquid fertilizers can make it much harder to cover the entire surface.
Flowering fertilizers used alongside bloom stimulants, other additives and additives, while controlling pH levels, can help you to achieve amazing yields of high quality cannabis.
