Hesi Phosphorus Plus: potent PK booster (7-5) for enhanced blooming and fruiting. Supports optimal phosphorus and potassium levels during flowering. Use with Hesi Bloom Complex for increased yields and robust plant development. Ideal for addressing phosphorus deficiencies and promoting prolonged blooms.
Hesi Phosphorus Plus is a potent PK fertiliser (7-5) specifically formulated to complement Hesi Bloom Complex. Designed for use from the middle of the bloom phase or when blooming noticeably slows, it provides essential phosphorus and potassium to support robust flowering and fruiting. This targeted approach ensures your plants receive the precise nutrients needed for optimal reproduction and efficient water and nutrient transport. For other flowering additives, check our flowering boosters page.
Key Benefits Of Using Hesi Phosphorus Plus
- Prolonged Bloom: Inspires and sustains prolonged flowering for both indoor and outdoor plants.
- Essential PK Boost: Delivers a 7-5 PK ratio, providing phosphorus and potassium crucial for the reproductive phase.
- Optimised Nutrient Balance: Complements Hesi Bloom Complex, ensuring a balanced nutrient profile throughout the bloom phase.
- Enhanced Water and Nutrient Movement: Supports the efficient transport of water and nutrients within the plant, promoting overall health and vigour.
How to Use Hesi Phosphorus Plus
Add Hesi Phosphorus Plus to your nutrient solution from the middle of the bloom phase or when blooming noticeably slows.
Dosage: Use 25ml per 10 litres of water, combine with Hesi Bloom Complex for best results. Monitor your plants and adjust dosage as needed. Always check your EC and PH levels after adding nutrients, check out our pH Management section for help with this.
For use in soil.
Available in 1 litre and 5 litres.
Frequently Asked Questions
Why shouldn't I use Hesi Phosphorus Plus before the middle of the bloom phase?
Before the middle of the bloom phase, the PK levels provided by Hesi Bloom Complex are sufficient. Introducing excessive phosphorus and potassium early on can hinder the absorption of other essential minerals and potentially cause deficiencies.Can I use Hesi Phosphorus Plus with other nutrient brands?
While technically possible, Hesi products are designed to work synergistically. Using them with other brands may lead to nutrient imbalances. For optimal results, it's recommended to stick with the Hesi nutrient line.Will using too much Hesi Phosphorus Plus harm my plants?
Yes, overfeeding can lead to nutrient burn. Always follow the recommended dosage and monitor your plants for any signs of stress.How do I know if my plants need phosphorus?
Phosphorus deficiency can manifest in several ways. Look for these signs:- Stunted growth, particularly in young plants.
- Dark green or purplish discolouration of older leaves, especially on the undersides.
- Delayed flowering or fruiting.
- Poor root development.
- In severe cases, older leaves may develop dead (necrotic) spots
It's important to note that these symptoms can sometimes be similar to other nutrient deficiencies, so a soil test is the most accurate way to confirm a phosphorus deficiency.
Can plants recover from phosphorus deficiency?
Yes, plants can often recover from phosphorus deficiency if it's addressed promptly. The key is to provide the plants with a readily available source of phosphorus, such as a phosphorus-rich fertiliser like Hesi Phosphorus Plus, and to ensure the soil pH is within the optimal range for phosphorus uptake.However, the extent of recovery depends on the severity and duration of the deficiency. If the plant has suffered significant damage, it may not fully recover. It is always best to try and prevent the deficiency in the first place, by providing correct nutrient levels throughout the plants growth cycle.
