Foliar feeding cannabis plants is a technique used by cannabis growers to provide nutrients directly to the leaves of the plant. This method involves spraying a nutrient solution, or teas onto the leaves, which allows for faster absorption than traditional root feeding.
Using Foliar Feeding
In the flowering stage of cannabis growth, foliar feeding can be beneficial for providing essential nutrients to the plant during a critical phase of development. Some nutrients that are commonly applied through foliar feeding in the flowering stage include potassium, phosphorus, and magnesium.
It is important to note that foliar feeding should not be relied upon as the sole source of nutrients for cannabis plants. Root feeding should still be the primary method of nutrient delivery, as foliar feeding is not as efficient and can lead to nutrient burn or other issues if overused.
When foliar feeding during the flowering stage, it is recommended to spray the nutrient solution onto the undersides of the leaves, as this is where most of the stomata (pores for gas exchange) are located. It is also important to avoid spraying during the hottest part of the day, as this can cause the leaves to burn.
Overall, foliar feeding can be a useful tool for cannabis growers looking to supplement their plants’ nutrient intake during the flowering stage, but it should be used in conjunction with root feeding and with caution to avoid overuse or damage to the plant.
Foliar Feeding Cannabis Plant Techniques
It is also important to use the proper equipment and techniques when foliar feeding cannabis plants in the flowering stage. A fine mist sprayer is recommended to avoid damaging the delicate flowers or causing excess moisture on the leaves, which can lead to mold or other problems.
Additionally, it is important to choose the right type of nutrient solution for foliar feeding in the flowering stage. Many nutrient solutions designed for foliar feeding contain a mix of micronutrients, which are essential for healthy growth and development of cannabis plants.
It is important to monitor the plants closely after foliar feeding to ensure that they are responding positively to the nutrient solution. If any signs of nutrient burn or other problems arise, it may be necessary to adjust the nutrient solution or reduce the frequency of foliar feeding.
Overall, foliar feeding can be a valuable tool for cannabis growers in the flowering stage, but it should be used with caution and in conjunction with other nutrient delivery methods. By following proper techniques and monitoring the plants closely, growers can help ensure healthy growth and optimal yields during this critical phase of cannabis development.
In addition to providing essential nutrients, foliar feeding can also have other benefits for cannabis plants in the flowering stage. It can help improve the plant’s overall health and vigor, as well as increase resin production and terpene levels, which are responsible for the plant’s aroma and flavor.
Foliar Feeding Cannabis for Pest Management
Some growers also use foliar feeding as a means of pest and disease control, as certain nutrient solutions can help deter pests and prevent the growth of harmful bacteria and fungi.
However, it is important to note that foliar feeding should not be relied upon as a replacement for proper pest and disease management techniques. Regular monitoring and preventative measures, such as proper sanitation and environmental control, should still be used to maintain a healthy growing environment.
Overall, foliar feeding can be a valuable technique for cannabis growers in the flowering stage, but it should be used carefully and in conjunction with other nutrient delivery methods and pest management techniques. With proper care and attention, growers can help ensure healthy growth and optimal yields during this critical phase of cannabis development.
Nutrients for Foliar Feeding Cannabis Plants
Finally, it’s important to choose high-quality nutrient solutions for foliar feeding in the flowering stage. Many nutrient solutions on the market are specifically formulated for cannabis and can provide the essential nutrients needed for healthy growth and development.
When selecting a nutrient solution, it’s important to consider the specific needs of the plants during the flowering stage. For example, cannabis plants in the flowering stage require higher levels of potassium and phosphorus to support flower development.
It’s also important to follow the manufacturer’s instructions when mixing and applying the nutrient solution. Overuse or incorrect mixing can lead to nutrient burn or other problems, so it’s important to measure and mix the solution carefully.
Overall, foliar feeding can be a valuable tool for cannabis growers in the flowering stage, but it should be used with care and in conjunction with other nutrient delivery methods. By selecting high-quality nutrient solutions, monitoring the plants closely, and following proper techniques, growers can help ensure healthy growth and optimal yields during this critical phase of cannabis development.
What Things Can Growers Use for Foliar Feeding Cannabis Flowering Plants?
- Liquid nutrient solutions: There are many nutrient solutions on the market that are specifically designed for foliar feeding cannabis plants in the flowering stage. These solutions often contain a mix of essential micronutrients, such as potassium, phosphorus, and calcium, which are important for healthy growth and development.
- Compost tea: Compost tea is a nutrient-rich liquid fertilizer that is made by steeping compost in water. It contains a variety of beneficial microorganisms and nutrients that can help improve soil health and plant growth.
- Fish emulsion: Fish emulsion is a liquid fertilizer made from fish waste. It’s high in nitrogen and other essential nutrients and can be a good option for foliar feeding during the vegetative stage.
- Seaweed extract: Seaweed extract is a natural fertilizer that is derived from seaweed. It contains a range of micronutrients, including potassium, calcium, and magnesium, as well as plant growth hormones that can help stimulate growth and flowering.
- Molasses: Molasses can be used as a natural source of carbohydrates and micronutrients for cannabis plants. It’s often added to compost tea or other nutrient solutions for foliar feeding.
It’s important to note that not all of these options may be appropriate for all cannabis growers or situations. It’s important to carefully research and select the best nutrient solution for your specific needs and to follow proper application techniques to avoid damaging the plants.
Timing Of Foliar Feeding Flowering Cannabis
It’s also important to consider the timing and frequency of foliar feeding in the flowering stage. Some growers prefer to foliar feed early in the morning or in the evening when temperatures are cooler, as this can help the plants better absorb the nutrients without risking damage to the leaves.
The frequency of foliar feeding will depend on the specific nutrient solution being used and the individual needs of the plants. In general, it’s recommended to foliar feed no more than once a week to avoid overuse and potential damage to the plants.
It’s important to note that foliar feeding should not be used as a substitute for proper soil or hydroponic feeding. Root feeding provides the majority of nutrients that the plant needs, and foliar feeding should only be used to supplement and enhance the plant’s nutrient intake.
Why Should You Stop Foliar Feeding Flowering Cannabis?
Foliar feeding during the flowering stage can have negative effects on the plant if continued too long into the flowering stage. Firstly, foliar feeding can cause the buds to develop a bad taste or aroma. This is because the nutrients from the foliar spray can stick to the buds, affecting their flavor and smell.
Secondly, foliar feeding can lead to nutrient burn. Nutrient burn occurs when the plant is given too many nutrients, causing the tips of the leaves to turn yellow or brown. This can negatively impact the plant’s overall health and reduce the yield. We recommend stopping foliar feeding in the flowering stage after the first four weeks of flowering to prevent any issues above.
When Should You Start Foliar Feeding Cannabis in Flowering?
We recommend starting foliar feeding cannabis in the vegetative stage of growth. However if you have not been foliar feeding we suggest that you start the first week of the flowering cycle.
Final Thoughts
In conclusion, foliar feeding can be a beneficial technique for cannabis growers in the flowering stage. When used properly and in conjunction with other nutrient delivery methods, it can help improve the overall health and vigor of the plants, increase resin and terpene production, and deter pests and diseases. By carefully monitoring the plants and following proper techniques, growers can help ensure healthy growth and optimal yields during this critical phase of cannabis development.
