Like all other types of feeding, there are a few rules and tips to follow to ensure you are liquid feeding properly.
Liquid feeding begins by preparing a solution in a mixing tank with water. This solution is fed to the roots to promote healthy, strong growth. Because liquid nutrients are readily available to the roots, they are fast-acting–which can also damage your plants if you feed them too much.
Some find that their plants thrive at a lower dose while others achieve the same results with more nutrients. The key is to be observant of your garden and pay attention to how the plants respond to fertilizer. Too little food and the plants will have stunted growth, while too much food can lead to nutrient burn and lockout.
Finding the best nutrient products for you will take time. Speak with your local store for recommendations to get started, but remember that spending the most money and buying all the products does not guarantee success.
All nutrients offer the nitrogen-phosphorus-potassium (NPK) ratio, which is shown as three numbers. These are the primary nutrients needed to grow plants. However, what a cannabis plant needs during its vegetative cycle is different from what it needs while flowering. A general rule of thumb is that a vegetative fertilizer should have high nitrogen, low phosphorus, and moderate potassium. An example would be an NPK ratio of 9-4-5. As a plant transitions into flowering, taper off the nitrogen and focus on phosphorus and potassium–seek a ratio around 3-8-7, for example.

Just as important as knowing when to liquid feed is knowing when not to administer nutrients. In the final two weeks before harvest, only give your plants water to help the plants remove the nutrient buildup in the buds. This process, which leads to a cleaner smoke, is called “flushing.”
In this article, we’ll look into what makes liquid fertilizer unique, as well as when and how to liquid feed cannabis plants.
Although liquid fertilizers may be the only input your plants need, be sure to also familiarize yourself with the other feeding methods discussed in this series.

If you buy a product with root stimulants in it then you should use it during the first two growth weeks and for two weeks after every time you transplant. If you have a flowering stimulant then you’ll need to use it once you flip the lights to 12 until the first flowers start appearing.
Once the female flowers begin showing then you’ll need to begin using flowering fertilizers. Just like in the growth period, you’ll need to start off little by little until you reach the maximum milliliters stated by the fertilizer manufacturer, alternating between pure water and fertilizers.
If your chosen range of liquids has a fattener with a high PK you’ll need to use it during the last phase of the flowering period, the fattening period.

Each brand has a different range of products, so depending on the brand you go with you’ll need to use more or less products for both growth and flowering, although in this article we’re just talking about WHEN to use them.
For the rest of the grow, regardless of what products you use, you will need to use them on every second watering or else you’ll burn out the roots. If you notice the plant getting yellow then you can use fertilizers twice in a row, but if it gets a dense dark green color then you’ll need to lay off on the fertilizers for a couple of waterings.
To start using nitrogen during the growth phase you’ll need to wait for your little plant to grow the roots out enough so that it becomes slightly stronger. It won’t need much more than some humidity to germinate and grow during the first few days, but once it begins growing aster then you’ll need to start using a growth fertilizer.
In this article we’re going to talk about when to start using fertilizers with cannabis. People always ask us when they should start using fertilizers on their plants, but honestly it depends on your grow method, the strain and the phase that the plant is in.
You should begin off with small dosages; if your product says 4ml/L for adult plants then you need to start off with 1ml/L, and only begin using it once the leaves on your plant have three points. Once those leaves appear you can start using your growth fertilizer in the irrigation water. Once the plant begins growing more then you should raise the dosage until you reach the maximum milliliters allowed, and always use it with every second watering.
Today we're going to talk about when to start using fertilizers with cannabis; depending on the phase your plant is in it will need certain nutrients.
