As cannabis cultivators become more experienced and refine their growing techniques, they often want to experiment with different types of fertilizer to see what works best for their plants. Some common questions cultivators ask are: “What’s the difference between veg and flower fertilizer for cannabis?” and “Which one should I use?”.
In general, veg fertilizer is used during the vegetative stage when plants are actively growing and producing leaves and stems. Flower fertilizer is used during the flowering stage when plants are producing buds. There are a few key differences between veg and flower fertilizer that cannabis cultivators should be aware of.
Veg fertilizer typically has a higher nitrogen content than flower fertilizer. Nitrogen is an essential nutrient for plants, helping them to grow and produce leaves. However, too much nitrogen can result in plants that are “leggy” with weak stems. For this reason, it’s important to follow your veg fertilizer instructions closely during the vegetative stage and to switch to flower fertilizer once plants begin to bud.
Flower fertilizer should have a higher phosphorus content than veg fertilizer. Phosphorus is another essential nutrient for plants, helping them to produce flowers and fruits. Unlike nitrogen, phosphorus is not mobile within plants. This means that plants can’t take up phosphorus that’s in the soil and store it for later use. For this reason, it’s important to use flower fertilizer that plants can absorb quickly to ensure they have enough phosphorus to produce buds.
Another key difference between veg and flower fertilizer is the ratio of macronutrients. Macronutrients are nutrients that plants need in large quantities, such as nitrogen, phosphorus, and potassium. The ratio of macronutrients in fertilizer is typically expressed as N-P-K, with the N representing nitrogen, the P representing phosphorus, and the K representing potassium.
Veg fertilizer typically has a higher Nitrogen ratio than flower fertilizer. Flowering nutrients usually have a higher ratio of phosphorus For example, a good ratio for veg fertilizer is 20-5-10, which means it contains 20% nitrogen, 5% phosphorus, and 10% potassium by total weight. In contrast, Reefertilizer Bloom for flower fertilizer is 5-30-20, which means it contains 3% nitrogen, 12% phosphorus, and 6% potassium.
Organic and synthetic fertilizers both have their pros and cons when it comes to cannabis cultivation.
Organic fertilizers are typically made from natural sources like compost or manure. They are often more expensive than synthetic fertilizers, but some growers believe they result in a higher quality product. Synthetic fertilizers are usually made from inorganic chemicals and can be more easily controlled than organic fertilizers. However, they can also be more harmful to the environment if not used heavily.
Synthetic fertilizers are different than organic fertilizers because they are made from inorganic chemicals. People use synthetic fertilizers because they are more easily controlled than organic fertilizers.
Cannabis cultivators should experiment with different types of fertilizer to see what works best for their plants. Remember, veg fertilizer is used during the vegetative stage and flower fertilizer is used during the flowering stage. Every plant can behave a little differently so be sure to watch carefully and try to understand what your plants are telling you.
