CES Bloom is the second component of the base three part blooming formula, to be used in conjunction with the Micro. Bloom is a phosphorus-heavy formula for enhancing flower production, as well as to encourage a plant to shift its hormonal signals from vegetative to flowering. Bloom also contains potassium to enhance the plant’ s photosynthetic rate and energy transfer throughout the plant. Bloom also contains lesser amounts of magnesium and sulfur, to help satisfy a plant’ s needs. Bloom is also added to CES’ s vegetative usage guides, in conjunction with the Micro and Grow.
