Botanicare Pure Blend Pro Bloom

Botanicare Pure Blend Pro Bloom is a complete bloom base nutrient formulated to support flowering, fruiting, and ripening plants with a phosphorus and potassium focused 2 3 5 NPK profile.

The formula combines essential plant nutrition with calcium, magnesium, and ingredients including fish meal, seaweed extract, magnesium sulfate, and humic acid. It can be used throughout the bloom cycle in soil, coco coir, container gardens, and hydroponic growing systems.

• NPK: Bloom Focused 2 3 5 Formula
• Calcium: Fortified With 1.0% Calcium
• Magnesium: Includes 0.5% Magnesium
• Application: Soil, Coco + Hydroponics

Botanicare's official feeding program introduces Pure Blend Pro Bloom when plants enter bloom transition and continues its use through flowering, fruiting, and final ripening.

2 3 5 Bloom Formula

Pure Blend Pro Bloom shifts the nutrient balance toward phosphorus and potassium to provide nutrition suited to flowering and fruiting plants. Its 2 3 5 analysis provides 2% nitrogen, 3% available phosphate, and 5% soluble potash.

Calcium & Magnesium Fortified

The formula contains 1.0% calcium and 0.5% magnesium, supplying important secondary nutrients alongside its primary NPK nutrition.

Complete Bloom Base Nutrient

Pure Blend Pro Bloom serves as the primary base nutrient during bloom, simplifying feeding while remaining compatible with additional Botanicare supplements when growers want to build a more comprehensive program.

Soil, Coco & Hydroponic Compatible

Pure Blend Pro Bloom can be incorporated into soil, coco coir, container, and hydroponic feeding programs. When growing in coco coir based media or using reverse osmosis water, Botanicare recommends adding 3 to 5 ml of Cal Mag Plus per gallon to the nutrient solution.

Part of the Pure Blend Pro Series

The following details were not included in the originally supplied product description and were confirmed directly through Botanicare's official product page. Pure Blend Pro Bloom is part of Botanicare's Pure Blend Pro family of one part base nutrients, sitting alongside Pure Blend Pro Grow for the vegetative stage and Pure Blend Pro Bloom Soil, a soil specific bloom formula. Botanicare describes the Pure Blend Pro line as combining natural minerals and organic extracts with the essential macro and micronutrients plants need, drawing sources of major and secondary elements plus trace minerals from land and sea.

Ingredient Sourcing

According to Botanicare's own Safety Data Sheet, the Pure Blend Pro Grow, Pro Soil, and Pro Bloom family is manufactured from dolomite, potassium carbonate, fish meal, seaweed extract, magnesium sulfate, and humic acid. This blend combines naturally mined mineral sources, including dolomite, potassium carbonate, and magnesium sulfate, with organic-derived inputs such as fish meal, seaweed extract, and humic acid. Botanicare offers a separate, dedicated organic product line under its Organicare brand; Pure Blend Pro is formulated as a natural mineral and organic-based nutrient rather than as a certified organic product.

Reduce Rate in Fortified Soil

If growing in a nutrient fortified potting soil or when using additional supplements, Botanicare recommends reducing the standard application rate by approximately 25% to avoid over-fertilizing.

Designed for Every Watering

Pure Blend Pro Bloom is intended to be used with every watering throughout the bloom cycle, rather than as an occasional supplement, providing consistent base nutrition as flowers and fruit develop.

Compatible Botanicare Supplements

Pure Blend Pro Bloom is designed to work alongside other Botanicare products, including Hydroplex, Cal Mag Plus, Rhizo Blast, Sweet, Hydroguard, and Liquid Karma, allowing growers to build a more complete bloom feeding program around this base nutrient.

Standard Feeding Schedule

Botanicare's standard Pure Blend Pro feeding chart recommends the following amounts per gallon:

• Bloom Transition Week 1: 25 ml
• Bloom Transition Week 2: 25 ml
• Bloom Transition Week 3: 27 ml
• Flowering / Fruiting Week 4: 30 ml
• Flowering / Fruiting Week 5: 30 ml
• Flowering / Fruiting Week 6: 30 ml
• Flowering / Fruiting Week 7: 25 ml
• Ripening Week 8: 20 ml

Expert Feeding Schedule

For growers following Botanicare's expert program, Pure Blend Pro Bloom is used at 15 to 18 ml per gallon throughout bloom transition and flowering, followed by 8 to 12 ml per gallon during ripening.

The expert recipe can incorporate Rhizo Blast, Liquid Karma, Cal Mag Plus, Silica Blast, Sweet, and Hydroplex at different stages of the cycle, providing a structured path for growers using the wider Botanicare nutrient system.

Mixing & Reservoir Guidelines

Botanicare recommends maintaining nutrient solution pH between 5.5 and 6.5 and keeping the solution between 68°F and 75°F. Nutrient solution should be used immediately after mixing or kept circulating to prevent settling.

For recirculating systems, maintain reservoir levels with fresh water and nutrients as required and change the solution weekly. For drain to waste systems, Botanicare recommends 10% to 20% runoff to help reduce potential salt buildup.

Recommended Use Practices

• Shake well before use.
• Measure accurately using clean equipment.
• Mix thoroughly into your water or nutrient reservoir.
• Adjust and confirm pH after fully mixing the solution.
• Reduce the application rate by approximately 25% when using nutrient fortified soil or additional supplements.
• Add Cal Mag Plus when growing in coco coir or using reverse osmosis water.
• Use with every watering throughout the bloom cycle.
• Follow the standard or expert feeding chart based on your experience level.
• Monitor plant response and adjust application rates as needed.
• Store the container tightly closed when not in use.

Storage

Store in the original container in a cool, dry, well ventilated area protected from direct sunlight. Keep the container tightly closed, upright, and properly labeled, and keep away from incompatible materials, food, and drink.
