Liquid fertilizers for plants – How and when to use them

Marijuana, just like any other plant, needs nutrients to grow and develop at its best. When plants are grown straight into the ground, soil provides most of the nutrients, but when they are grown in a pot, the grower has to provide the necessary nutrients to make sure that the plant doesn’t suffer deficiencies and is able to provide a generous yield. Liquid fertilizers for plants are the easiest and most appropriate option to reach the set goal.

Liquid fertilizers contain all the nutrients that plants need at each vital cycle. Rooting additives help the roots to penetrate into the soil easily and effectively. Growth fertilizers provide a nitrogen boost that promotes strong leaves and stems while increasing the plants’ immune system and getting them ready for the flowering period, when they need a bit of potassium and phosphorus to grow good quality buds.

When to add liquid fertilizers for plants and how much do they need

These essential nutrients can be added in two ways, either through the substrate or by using fertilizers. The last ones get mixed with irrigation water and are applied to the plants in liquid form to make sure the roots absorb it.

The needed amount varies between the brand, the type of plant and its phase. Plants don’t need the same amount of nitrogen during growth than during the flowering period, the same way they don’t need the same amount of water when they are rooting than when the plant is fully grown. Therefore, getting to know the different phases of the plants and learning to interpret their needs takes time, but the different brands always provide a guide chart with the amount of ml per liter of water to be used.

When do you need to use liquid fertilizers for plants?

There are various ways to use fertilizers. Some growers prefer to alternate only water irrigations with fertilizers while others only water the plants with the nutrients incorporated. It also depends on the stage of the plant, if it’s an indoor or outdoor crop or the weather in the area. Very sunny areas will force the grower to water more often because the substrate dries faster.

However, the same way it happens with the amount and use mode, fertilizing brands normally provide clear indications explaining when to water and when not to.
