Grotek Final Flush is formulated to remove excess salts from the plant medium, to ensure a cleaner, tastier and more aromatic harvest. Plants tend to absorb excess nutrients and store them in plant tissues. By purging nutrients from the root zone, plants are forced to convert accumulated salts into secondary metabolites that improve harvest quality. The result is a harvest of the highest quality, with the expected taste and aroma.

• Flushes excess salts away from the roots
• Mitigates the damage from over-fertilisation
• Enhances aroma and flavour qualities

Application: For best results, use during the final week of flowering to flush plants of excess nutrients or at any time to cleanse the plant medium of accumulated nutrients.

• 2 ml per 1 L of water
• Watch for visible signs of excess fertiliser salts, such as a white, powdery residue appearing on the surface of the plant medium!
• Safe to use during the plant growth period as well.

Soil/Coco:

• Before harvest: add Final Flush Blueberry 7-10 days before harvest to remove unnecessary salts and fertilisers.
• Salt build-up: add Final Flush Blueberry generously and allow the excess solution to drain through the bottom of the container/pot. Repeat if necessary and then wait 1 week, before resuming the regular feeding programme.

Hydroponics:

• Add Final Flush to clean water in the nutrient reservoir and let the system run for about one hour.

Derived from:

• Ascorbic acid, citric acid

Contents:

• Ascorbic acid 0.6%
• Citric acid 0.6%

Grotek Blossom Blaster is a concentrated formula, providing an abundance of nutrients required for rapidly developing flowering sites.

• NPK: 0-48-31
• Helps support rapid development
• Stimulates abundant flowering

Blossom Blaster contains high levels of phosphorus and potassium, two of the most important macronutrients required by plants. Potassium supports the movement of water, nutrients and carbohydrates throughout the plant, while phosphorus supports the overall structure, plant strength and vitality throughout all stages of plant growth. This highly concentrated formula can be used from early plant development through flowering and bud opening.

Application:

• Soil/Coco coir/Hydroponics: 1g per 10l of water. Repeat once more after two weeks.

Derived from:

• Monopotassium phosphate

Contents:

• Available phosphate (P₂O₅) 48%
