When to stop fertilizing cannabis plants?

Written by on 9 February, 2022

Both photoperiodic and auto-flowering marijuana strains require certain nutrients to grow and develop fully. Depending on the stage of growing they are in, they will need more of one type of nutrient than another.

In the vegetative phase, for example, plants generally need significant amounts of nitrogen, while in flowering, fertilizers should be especially rich in potassium and phosphorus.

Well, as we mentioned, providing nutrients to your girls is essential for their development, but when should you stop fertilizing? Take a look at this post, we will tell you about it.

Finish the fertilization cycle

In the last phase of flowering, the maturation stage, the buds are generally already quite large and dense, the trichomes go from being transparent to have a milky color, in short. During this period, growers recommend reducing fertilization gradually.

Also, when there are 1 or 2 weeks left before harvest, growers advise stopping fertilizing cannabis strains completely. You see, many of them believe that if fertilizers are applied until the end of the growing process, the resulting buds will have a chemical taste, therefore, as we mentioned, they eliminate the use of fertilizers at that time and wash the roots with pure water to get better tasting buds.

Once you check that the buds of your flowers are fully ripe you can begin to make the desired harvest.
