Can you mix growth and flowering fertilizer?

Mixing growth and flowering fertilizers is a common practice among growers looking to optimize the development of their plants in the transition stages between vegetative growth and flowering. This is because, during this phase, plants need both nitrogen , essential for robust leaf and stem development, and phosphorus and potassium , which favor flower formation. However, the mixture must be done carefully, respecting the proportions to avoid over-fertilization problems.

An effective way to mix these fertilizers is to use reduced doses of each, making sure not to exceed the recommended concentration of nutrients. It is crucial to know the specific needs of the plant and its stage of development. This way, essential nutrients can be supplied without saturating the substrate or upsetting the nutrient balance.

It is also important to monitor the pH and electroconductivity (EC) of the nutrient solution when mixing growth and flowering fertilizers. Keeping these parameters within the proper range ensures that plants can efficiently absorb the nutrients supplied and avoids problems such as nutrient lockouts or deficiencies.

How to use liquid fertilizer?

Liquid fertilizer is a popular choice among growers due to its ease of application and rapid absorption by plants. To use it correctly, it is important to dilute the fertilizer in water following the manufacturer's instructions, as excessive concentration can damage roots and compromise plant development.

Liquid fertilizer can be applied by direct irrigation into the substrate or by foliar spraying. When irrigating, make sure that the solution reaches the roots evenly to ensure proper distribution of nutrients. If you opt for foliar spraying, do the procedure during the early morning or late evening hours to avoid sunburn on the leaves.

It is advisable to create a fertilization schedule that is tailored to the specific needs of the plants according to their stage of growth. Likewise, monitoring the state of the leaves and general development can indicate whether it is necessary to adjust the frequency or concentration of the liquid fertilizer.

Is it possible to mix growth and flowering fertilizer when growing cannabis?

Yes, it is possible to mix growth and flowering fertilizers when growing cannabis, especially during the pre-flowering stage , when the plant begins to form flowers but still needs additional nitrogen support. At this stage, a combination of both types of fertilizer helps to cover the specific nutritional needs of the plant.

However, it is essential to do so in a controlled manner , using balanced proportions and avoiding overloading the plant with nutrients. It is important to observe the signals that the plant gives off, such as the color and vitality of the leaves, to ensure that the mixture is beneficial and does not cause problems such as toxicity.

How to combine subscriptions?

To combine growth and flowering fertilizers , the first thing to do is to calculate the appropriate doses of each one according to the needs of the plants and the manufacturer's instructions. Generally, it is recommended to reduce the dose of both fertilizers by half to avoid saturating the substrate. For example, if the manufacturer suggests 2 ml/L of each fertilizer, you can use 1 ml/L of each.

Make sure to mix the fertilizers into the irrigation water in a specific order: first completely dissolve one fertilizer before adding the other. This prevents the nutrients from reacting with each other and forming precipitates that the plants cannot absorb. It is also key to measure the pH and adjust it to the proper range (5.5-6.5 for growing in soil) after adding the fertilizers.

Finally, when combining fertilizers, it is good practice to monitor the condition of your plants regularly for any signs of nutrient deficiency or excess . If you notice problems such as yellow leaves or burnt tips, adjust the mixture immediately to protect the healthy development of your plants.

When to stop mixing?

You should stop mixing growth and flowering fertilizers once the plant fully enters the flowering phase . At this stage, nitrogen requirements decrease significantly, while the demand for phosphorus and potassium increases to encourage the development of dense, resinous flowers. At this point, flowering fertilizer should be used exclusively.

It is advisable to perform a root flush at the end of the transition stage to remove any nutrient buildup that may interfere with the efficient uptake of flowering fertilizers. This ensures that the plants can focus on producing high-quality flowers without carrying away excess residual nutrients.

When choosing liquid fertilizers, it is crucial to consider the quality of the product, compatibility with your type of crop, and the specific needs of your marijuana plants. Additionally, you should follow dosing instructions carefully to avoid over-fertilization.
