Cutting Edge Solutions Bloom, 2.5 gal

Phosphorus-Rich Bloom Nutrient in the CES 3-Part System, 2.5 Gal

During the flowering phase, plant nutritional demands shift significantly from the vegetative stage, and phosphorus becomes the primary macronutrient driver of flower development, supporting the energy-intensive processes of flower initiation and expansion. A bloom fertilizer with an elevated phosphorus profile, balanced with potassium and secondary nutrients, carries the plant through this demanding phase.

The 2.5 gal size fits a regular indoor grow room feeding CES Bloom to a standing flowering-phase reservoir.

Key Features & Benefits

• Phosphorus-heavy bloom formula — elevated phosphorus content supports flower initiation and development during the blooming phase.
• Potassium for photosynthesis — enhances photosynthetic rate and energy transfer throughout the plant during flowering.
• Magnesium and sulfur included — lesser amounts of magnesium and sulfur round out the plant's secondary nutrient needs during bloom.
• Pairs with CES Micro — used together with CES Micro as the bloom-phase leg of the CES 3-part base nutrient program.
• Also called for in transition feeds — some CES vegetative-to-bloom transition schedules bring Bloom in alongside Micro and Grow before Grow is dropped.

Who Should Use CES Bloom

Hydroponic and indoor growers running the CES 3-part base nutrient system who need a phosphorus-heavy bloom component to pair with CES Micro once plants move into the flowering phase.

About Cutting Edge Solutions

Cutting Edge Solutions manufactures its nutrient line domestically, running formulation, bottling, and shipping in-house with an on-staff microbiologist supporting quality control. Bloom belongs to the company's Base Family alongside Micro and Grow, the three-part foundation every other CES product in the Strength and Advanced Molecular families is built to layer onto rather than replace. The company relocated its production facility from Santa Rosa, California to White City, Oregon in 2022, while remaining family-owned.

Frequently Asked Questions

What is CES Bloom?

CES Bloom is the phosphorus-heavy bloom fertilizer in the Cutting Edge Solutions 3-part base nutrient system. It supports flower production together with CES Micro and contains potassium, magnesium, and sulfur to round out the plant's needs during flowering.

When do I switch from CES Grow to CES Bloom?

When transitioning the plant from vegetative growth to flowering, remove CES Grow from the nutrient solution and introduce CES Bloom alongside CES Micro. Follow the CES usage guide for specific timing and transition ratios.

Is CES Bloom used with CES Micro or on its own?

CES Bloom is used together with CES Micro as part of the CES 3-part system rather than as a standalone base nutrient. Micro supplies nutrients that Bloom doesn't include, so both are needed for a complete base solution during flowering.

Why is CES Bloom phosphorus-heavy?

Phosphorus is the primary macronutrient driver of flower development. An elevated-phosphorus bloom fertilizer gives the plant the nutrient base it needs for flower initiation and expansion during the flowering phase.

How much CES Bloom do I mix per reservoir?

Mixing rates depend on plant stage and reservoir size, so follow the CES usage guide for the specific ratio of Micro to Bloom at each point in flowering. Always dilute CES Micro into fresh water first, then add Bloom at the specified rate.
