When Do You Stop Feeding Pot Plants?

Knowing when to stop feeding your pot plants is crucial in ensuring they develop and mature properly. Overfeeding your plants can be detrimental as it can lead to nutrient burn, stunted growth, poor yields and even plant death. On the other hand, underfeeding can cause nutrient deficiencies which can also hinder growth and lead to poor yields. In this article, we will discuss when you should stop feeding your pot plants to optimize their growth and ensure healthy yields.

When To Stop Feeding During The Vegetative Phase?

The vegetative phase of pot plant growth is characterized by rapid growth and expansion of the plant. This is the time when the plant develops leaves, stems, and branches. During this stage, pot plants require a lot of nutrients to maximize their growth potential. Most growers recommend feeding the plant during the vegetative phase until it reaches about two-thirds of its desired height.

Once the plant reaches two-thirds of its desired height, you can reduce the amount of nutrients to prevent nutrient burn. This will also help prevent the plant from becoming too tall and leggy, which can make it difficult to manage during flowering.

When To Stop Feeding During The Flowering Phase?

The flowering phase of pot plant growth is when the plants begin to produce buds that will eventually turn into flowers. This is the time when plants require less nitrogen and more phosphorous and potassium. During the flowering phase, it is important to gradually reduce the amount of nutrients to avoid nutrient burn and to flush out any excess nutrients that may have accumulated in the soil.

Most growers recommend stopping feeding the plant with nutrients about two weeks before harvest. This will allow the plant to use up any excess nutrients in the soil and produce cleaner, smoother-tasting buds. Some growers also recommend flushing the soil with plain water during the last week or two before harvest to ensure that any excess nutrients are removed from the soil.

Signs That It's Time To Stop Feeding

There are some signs that your plant may be ready for you to stop feeding it. These signs include:

Yellowing leaves

Burnt tips or edges on leaves

Slow growth or stunted growth

Darker or browner leaves

Reduced yield

If you notice any of these signs, it may be time to stop feeding your plant with nutrients to prevent further damage.

Conclusion

Knowing when to stop feeding your pot plants is crucial in ensuring optimal growth, healthy yields, and preventing nutrient burn or deficiency. During the vegetative phase, it is recommended to stop feeding your plant when it reaches about two-thirds of its desired height to prevent nutrient burn and to keep the plant manageable. During the flowering phase, it is important to gradually reduce the amount of nutrients and to stop feeding the plant about two weeks before harvest. By following these guidelines and paying attention to signs that your plant may be ready to stop feeding, you can ensure a successful harvest and enjoy the fruits of your labor!
