Gold Label Ultra LED No.1 & No.2 – Base Feed A+B for LED

A matched two-part base feed built around LED spectrum, not legacy HPS

The Gold Label Ultra LED No.1 & No.2 is a two-part mineral base nutrient sold as a matched pair — No.1 (Grow) and No.2 (Bloom) — formulated specifically for crops grown under full-spectrum LED lighting. Each bottle covers one growth stage, so the ratio between the two shifts as the plant moves from vegetative growth into flowering, rather than relying on a single fixed-ratio feed through the whole cycle.

Key Benefits

• Two-part No.1/No.2 system lets you shift the feed ratio between grow and bloom stages.
• No.1 (Grow): NPK 4-0-2 +Ca7, weighted for vegetative development.
• No.2 (Bloom): NPK 2-3-6 +Mg7, weighted for flowering and fruiting.
• Formulated for LED spectrum growing, pairing with the Ultra LED Boost additive.
• High-concentration liquid minerals keep dose rates economical.
• Dutch-manufactured to Gold Label's usual consistency and quality control.

A base feed tuned for HPS growing doesn't always translate cleanly to an LED-lit room, where the light spectrum and canopy response differ. Gold Label built the Ultra LED range from the ground up around LED growing, so the No.1/No.2 ratio and the calcium/magnesium loading are matched to how plants actually take up nutrients under that light.

How to Use

• Vegetative stage: weight the feed towards No.1, following the manufacturer's dose chart for your medium.
• Flowering stage: shift the ratio towards No.2 as the plant moves into bloom.
• Mix No.1 and No.2 separately into the reservoir before combining, then check EC and pH before feeding.
