Grow More® Mendocino Producer's Choice Base 14.5-0-0 — 25 lb

Pure Nitrogen Powder Built for Independent N Adjustment in a Multi-Part Program

Correcting a nitrogen deficiency with a complete fertilizer means also adding phosphate and potassium the plant may not need, throwing off a carefully calibrated feeding program. Grow More Mendocino Producer's Choice Base 14.5-0-0 solves that with a concentrated nitrogen-only powder at 14.5% total nitrogen and zero phosphate or potassium, giving growers surgical precision to raise nitrogen alone without disturbing existing P:K ratios.

As part of the Mendocino Producer's Choice line, the 25 lb bag dissolves completely with no residue and can be added at any stage of a feeding program, whether correcting a deficiency, pushing vegetative growth, or building a custom nutrient solution from scratch.

Key Features & Benefits

• 14.5% Pure Nitrogen, No P or K: Delivers nitrogen independently, giving growers precise control over macronutrient ratios without disrupting existing feed formulas.
• Nitrogen Deficiency Correction: Quickly addresses yellowing leaves, slow growth, and pale foliage by boosting available nitrogen without adding unneeded P or K.
• Custom Formula Building Block: A clean nitrogen source for growers building custom nutrient programs from scratch.
• Versatile Application Timing: Can be applied at any growth stage where additional nitrogen is warranted.
• 100% Water-Soluble: Dissolves completely with no sediment, suitable for drip, flood-and-drain, NFT, and foliar applications.

Who Should Use This

Advanced growers who manage macronutrient ratios independently and need a clean nitrogen source to supplement or balance an existing nutrient program are the direct fit, particularly those building custom formulas or correcting nitrogen deficiencies without touching phosphate and potassium levels.

Frequently Asked Questions

When would I use a 14.5-0-0 formula instead of a complete fertilizer?

It's used when nitrogen needs adjusting independently without changing the P:K balance of an existing nutrient program. This matters most in advanced nutrient management where each macronutrient is calibrated separately for a specific crop stage or response.

What forms of nitrogen does this product contain?

It contains multiple nitrogen forms, ammoniacal and water-soluble nitrogen, to support rapid uptake and sustained availability. Check the product label for the specific guaranteed analysis breakdown.

Can I use this as my only nitrogen source?

It can serve as a nitrogen source, but it provides no phosphate, potassium, or micronutrients. It's most effective as part of a complete nutrient program, used to supplement or fine-tune nitrogen rather than as a standalone complete fertilizer.

Is this suitable for use during flowering?

It can be used during flowering if nitrogen correction is needed, but most bloom-stage programs reduce nitrogen to encourage phosphate and potassium uptake for flower development. Use carefully during late flower and discontinue as harvest approaches.
