£111.95

A two-part flowering base nutrient with pH Perfect technology, formulated to provide balanced macro, secondary and micronutrition throughout active flowering.

Advanced Nutrients pH Perfect Sensi Bloom A+B is a complete two-part liquid base nutrient for the flowering stage. Part A and Part B work together to provide the nutritional profile required as plants move from vegetative growth into active flower and fruit development.

Part A incorporates amino acid complexes designed to support efficient nutrient uptake, while Part B provides the flowering-focused NPK balance. Humic acid derived from leonardite further supports chelation and nutrient availability within the root zone.

Advanced Nutrients' pH Perfect technology is built into the formula to manage nutrient-solution pH when the complete A+B programme is mixed and used as directed. The 10L format is particularly well suited to larger reservoirs, commercial growing areas and high-throughput feeding programmes.

Why choose pH Perfect Sensi Bloom A+B?

  • Complete flowering base nutrient – Parts A and B provide complementary nutrition throughout active flowering.
  • Flowering-focused nutrient profile – Part B has an NPK of 2-4-8 to support the changing nutritional demands of reproductive growth.
  • Amino acid complexes – incorporated into Part A to support efficient nutrient uptake.
  • pH Perfect technology – designed to manage nutrient-solution pH when the complete programme is mixed and used as directed.
  • Humic acid from leonardite – supports chelation, nutrient availability and pH buffering within the root-zone environment.
  • Simple flowering rate – both components are used at 4ml/L throughout active flowering.
  • Suitable for hydroponic growing – compatible with a wide range of hydroponic media and continuous liquid-feed systems.
  • 10L format – a practical option for larger crop areas and growers preparing nutrient solution regularly.

What is Sensi Bloom A+B suitable for?

Sensi Bloom A+B is designed for the flowering and reproductive phase of the crop cycle. It follows pH Perfect Sensi Grow A+B once vegetative development is complete and the crop moves into flowering.

It is suitable for indoor and outdoor cultivation, regular watering and irrigation systems. Advanced Nutrients also specifies the formula for diverse hydroponic growing media and continuous liquid-feed systems including aeroponics, drip irrigation and emitters, nutrient film technique (NFT), flood and drain and deep water culture (DWC).

The standard Sensi Bloom formulation is also coco coir safe. Growers working specifically around the nutritional characteristics of coco can alternatively use the dedicated pH Perfect Sensi Coco Bloom A+B formulation.

How to use pH Perfect Sensi Bloom A+B

Shake both components thoroughly before use. Add Part A to the required volume of water and mix thoroughly. Add Part B separately and mix again. Never combine the concentrated Part A and Part B products directly before dilution.

During active flowering, use 4ml/L of Part A plus 4ml/L of Part B. Continue at this rate throughout the active flowering phase, then discontinue both components when the crop reaches its final flush.

For a 10L nutrient solution, use 40ml Part A + 40ml Part B. For 50L, use 200ml Part A + 200ml Part B. For a 100L reservoir, use 400ml Part A + 400ml Part B.

The 4ml/L rate applies to each component individually. It means 4ml/L of Part A and 4ml/L of Part B, rather than 4ml/L divided between the two components.

Advanced Nutrients pH Perfect Sensi Bloom A+B FAQs

What is Advanced Nutrients pH Perfect Sensi Bloom A+B?

Sensi Bloom A+B is a two-part liquid base nutrient formulated for flowering and reproductive growth. Parts A and B work together to provide the macro, secondary and micronutrients required throughout the flowering phase.

How much Sensi Bloom A+B should I use per litre?

Use 4ml/L of Part A plus 4ml/L of Part B throughout active flowering. Both components are applied at the same rate.

How much Sensi Bloom A+B do I need for 10 litres?

For 10 litres of nutrient solution, use 40ml of Part A plus 40ml of Part B.

How much Sensi Bloom do I need for a 100L reservoir?

A 100L reservoir requires 400ml of Part A plus 400ml of Part B at the standard 4ml/L flowering rate.

Do I use Sensi Bloom Part A and Part B together?

Yes. Sensi Bloom is a true A+B base nutrient. Parts A and B are used together at equal rates throughout active flowering.

Can I mix Sensi Bloom A and B concentrates together?

No. Add Part A to the water and mix thoroughly before adding Part B. Never mix the undiluted concentrates directly together.

What is the NPK of Advanced Nutrients Sensi Bloom?

Advanced Nutrients lists pH Perfect Sensi Bloom Part A as 3-0-0 and Part B as 2-4-8. The two components are formulated to be used together as the flowering-stage base nutrient.

When should I start using Sensi Bloom?

Move from Sensi Grow A+B to Sensi Bloom A+B as the crop transitions from vegetative development into flowering. Continue Sensi Bloom throughout the active flowering phase.

When should I stop using Sensi Bloom?

Continue using both components throughout active flowering, then discontinue Sensi Bloom when the crop reaches its final flush.

Can pH Perfect Sensi Bloom be used in hydroponics?

Yes. Sensi Bloom is designed for hydroponic growing media and continuous liquid-feed systems including aeroponics, drip irrigation, NFT, flood and drain and deep water culture.

Can standard Sensi Bloom be used in coco?

Yes. Advanced Nutrients lists the standard pH Perfect Sensi Grow and Bloom range as coco coir safe. A separate Sensi Coco formulation is available for growers who want a nutrient specifically developed around the nutritional characteristics of coco.

What does pH Perfect technology do?
