Bigger, denser blooms from a complete bloom-stage feed
Advanced Nutrients Sensi Bloom A&B is a premium two-part base nutrient formulated specifically for the bloom stage and suitable for hydroponics, coco and soil. It supplies a complete blend of macro, secondary and micronutrients to support abundant flowering, improved bud density and higher yields. Its pH Perfect Technology automatically helps hold the root zone at the optimal pH when used as part of a compatible programme, improving nutrient uptake and reducing manual pH adjustment, while chelated micronutrients, humic acids, fulvic acids and amino acids support plant health throughout flowering.
Key Benefits
- Complete two-part bloom nutrition - macro, secondary and micronutrients
- pH Perfect Technology holds root-zone pH and cuts manual adjustment
- Chelated micronutrients for strong, reliable nutrient uptake
- Humic, fulvic and amino acids to support overall plant health
- Larger, denser flowers with consistent bloom performance
- Cross-media use across hydroponics, coco and soil
- Programme compatible with the full Advanced Nutrients range
Fixing poor nutrient uptake and airy buds during flowering
Flowering plants need higher phosphorus, potassium and trace elements to build large, dense flowers; fall short and you get poor uptake, airy buds and lower yields. Sensi Bloom A&B delivers balanced nutrition across the whole bloom stage while pH Perfect keeps nutrients available at the roots, helping plants finish denser and more consistently in a tent, grow room or hydro system.
How to Use
- Fill your reservoir or watering container with fresh water
- Add Part A first and mix thoroughly, then add Part B
- All media (bloom): use 4ml of Part A and 4ml of Part B per litre throughout the flowering cycle
- Stir well before adding any additional supplements
- Feed with every watering or reservoir change during bloom
- Monitor EC and adjust feed strength to suit your crop
- Never mix Part A and Part B together in concentrated form - this causes nutrient lockout through precipitation
