Yielding Potent Cannabis Plants with Liquid Nutrients: What is Liquid Feeding?

Written by Bethan Jenkins

Are you getting involved in the cannabis agricultural space? If so, the topic of liquid feeding is one that you must be well-versed in. A plant’s nutrient uptake profile will influence the quality of the final product. Rather than forking money for chemical fertilizers that could potentially harm your plants, opt for a natural nutrient-rich solution, such as liquid fertilizer.

What is the purpose of liquid fertilizer for cannabis?

Just like any other type of plant, cannabis requires a select assortment of nutrients in order to thrive. Liquid fertilizing of cannabis can maximize yields and bolster bud quality. Suitable for gardens with and without soil, liquid feeding is a fertilization tactic that will give you control over what nourishment your crop gets.

How will I know when to use a liquid fertilizer for cannabis?

Dedicate a liquid feeding schedule according to the type of cannabis you are cultivating. A hydroponic setup will require constant exposure to liquid fertilizer, whereas a soil-grown garden will not be as dependent on liquid feeding.

When growing cannabis in soil, use fertilizer just a few times until you notice flowering. Two weeks prior to harvest, provide plants with water. By doing so, you can eliminate nutrient build-up or “flush” the buds.

“Nutrient lockout” may happen if the plants are not taking in nutrients properly. Avoid this by using organic nutrients and checking pH levels daily.

Should I use a feed chart for liquid feeding?

Establishing a liquid feeding schedule is the key to successfully identifying trends and determining how your plants respond to certain nutrients. You can accomplish this with a feed chart, which is essentially a grid. Feed charts are much like a daily journal, in the sense that you will use it to record everything, from the nutrients per gallon of solution, to the way your plants look after being fed.

Additional Tips for Growing Cannabis with Liquid Fertilizer

Liquid nutrients come in many forms. Choose yours wisely by paying attention to the nitrogen-phosphorus-potassium (NPK) ratio. Ideally, liquid fertilizer should contain high levels of nitrogen, low levels of phosphorous and moderate levels of potassium, so you might opt for something with a ratio that looks like: 8-5-6.

Begin with a small liquid dose and work your way up. Monitor your plants multiple times per day to ensure they are responding well to liquid nutrients, which can be delivered through hoses, drip lines and misters.
