Grow More® All-Season's Plant Food 20-20-20 — 1 oz

Balanced Formula With Medium Potential Acidity Built to Push Back Against Alkaline Water

Tap and well water in many regions runs alkaline, and over time that alkalinity nudges soil pH upward, locking out iron, manganese, and other micronutrients even when they're present. Grow More All-Season's Plant Food 20-20-20 is a fully balanced, 100% water-soluble fertilizer built with medium potential acidity, specifically chosen to help counteract that gradual pH creep rather than just supply nutrients.

The 1 oz packet delivers equal parts nitrogen, phosphorus, and potassium — a genuine all-season ratio that supports vegetative growth, root development, and basic flowering without requiring a stage-specific switch, and the formula works equally well applied as a foliar spray or soil drench.

Key Features & Benefits

• 20-20-20 Balanced NPK: Equal nitrogen, phosphorus, and potassium supports vegetative growth, root development, and flowering across the season without needing a formula change.
• Medium Potential Acidity: The acidifying effect helps offset alkalinity common in tap and well water, nudging soil toward a more plant-favorable pH without a separate corrector.
• Counteracts Alkaline Water: Purpose-built for growers whose irrigation water pushes soil pH up over time, reducing micronutrient availability.
• Versatile Application: Works as a foliar spray for fast uptake or a soil drench for root-zone feeding.
• Organic Compatible: Formulated to work alongside organic inputs in a blended nutrition program.

Who Should Use This

Home gardeners, container growers, and small-scale cultivators who want one easy, balanced fertilizer for the whole season are the direct fit, especially in regions where alkaline tap water is a known issue. The 1 oz size suits growers who want to trial the formula or only need occasional small-batch mixing.

Frequently Asked Questions

What does "medium potential acidity" mean in a fertilizer?

Potential acidity describes the acidifying or alkalizing effect a fertilizer has on soil as plants take it up. A medium rating means this formula has a moderate acidifying effect, enough to counteract gradual pH rise from alkaline water without over-acidifying the growing medium.

How does alkaline irrigation water affect plant nutrition?

Alkaline water raises soil and media pH over time, reducing the availability of iron, manganese, zinc, and copper, which become insoluble above roughly pH 7.0 to 7.5. That produces micronutrient deficiency symptoms, particularly interveinal chlorosis from iron shortage, even when those nutrients are physically present.

Can this product be used year-round?

Yes, the 20-20-20 balanced ratio is built for season-long use across plant types and growth stages, providing adequate NPK for vegetative growth, root development, and basic flowering without the extremes of a stage-specific formula. Many growers keep it as their standard everyday feed and switch to a stage-specific formula only when they want to push a particular growth phase harder.

What does organic compatible mean for this product?

It means the formula can be used alongside organic inputs like compost, worm castings, or kelp meal without undermining those materials. It does not mean the product itself is OMRI certified for organic production.
