Cutting Edge Solutions Bloom, 15 gal

Cutting Edge Solutions Bloom — 3-Part Base Bloom Fertilizer, 15 gal

The CES 3-part base nutrient system divides macronutrient delivery into three dedicated bottles. Bloom is the phosphorus-rich component in this system, formulated to support flower production and energy transfer during the flowering stage. While primarily a bloom-phase product, Bloom is also used at low rates alongside Micro and Grow during the vegetative phase to provide balanced phosphorus across the entire grow cycle.

CES Bloom delivers phosphorus as the primary macronutrient alongside potassium for photosynthesis and energy transfer, and includes magnesium and sulfur for comprehensive secondary nutrient coverage. During bloom, Bloom replaces CES Grow and is used together with CES Micro to form the complete base nutrient program. Available in fifteen gallons.

Key Features & Benefits

• Phosphorus-rich bloom component — provides phosphorus as the primary macronutrient to support flower initiation, development, and energy transfer during the flowering stage.
• Potassium for photosynthesis and energy transfer — potassium content supports photosynthetic function and the transfer of energy and sugars throughout the plant during bloom.
• Magnesium and sulfur — secondary nutrients magnesium and sulfur are included for comprehensive macronutrient coverage alongside the primary P and K components.
• Also used in the vegetative phase — used at low rates alongside CES Micro and CES Grow during the vegetative phase to provide balanced phosphorus from the start of the nutrient program.
• Part of the CES 3-part base — used in combination with CES Micro (constant base) and CES Grow (veg phase) or Micro alone (bloom phase) as the phosphorus component of the complete base nutrient system.

Who Should Use CES Bloom

Growers using the CES 3-part base nutrient system who need the phosphorus-rich bloom component to pair with CES Micro during the flowering stage, or who are running the complete 3-part system through both vegetative and bloom phases.

Bloom Phase Transition

When transitioning from the vegetative to the bloom phase, CES Grow is phased out and replaced with CES Bloom. CES Micro continues to be used throughout. Bloom is introduced at the start of the flowering cycle and continues through the end of bloom. Follow the CES usage guide for the correct Micro-to-Bloom ratios at each week of the bloom cycle and for recommendations on when to taper Bloom dosing as harvest approaches.

Frequently Asked Questions

What is CES Bloom?

CES Bloom is the phosphorus-rich bloom component of the Cutting Edge Solutions 3-part base nutrient system. It is used during the flowering stage alongside CES Micro to provide the primary macronutrient base for flower production, and also at low rates during the vegetative phase for balanced phosphorus throughout the cycle.

When does CES Bloom replace CES Grow?

CES Bloom replaces CES Grow when the plant transitions from the vegetative to the flowering stage. CES Micro continues to be used throughout both phases. The CES usage guide provides specific ratios for transitioning from the veg formula (Micro + Grow) to the bloom formula (Micro + Bloom).

What nutrients does CES Bloom provide?

CES Bloom provides phosphorus as the primary macronutrient alongside potassium for photosynthesis and energy transfer, with magnesium and sulfur included as secondary nutrients for comprehensive coverage.

Is CES Bloom used during the vegetative phase?

Yes — CES Bloom is also used at low rates during the vegetative phase alongside CES Micro and CES Grow to provide balanced phosphorus from the start of the nutrient program. The CES 3-part system uses all three components across both phases, with ratios shifting as the plant moves from veg to bloom.

How does CES Bloom work with the rest of the CES system?

CES Bloom is one of three components in the CES base nutrient system, used alongside Micro (constant throughout) and Grow (vegetative phase). During bloom, Bloom and Micro together form the complete base nutrient formula. Bloom is then supplemented with CES additives from the CES stack according to the usage guide.
