Grotek Insta-Green 3-0-0 Greening Solution
This is a fast-acting greening solution for plants that have lost their color. Grotek formulates it to bring stressed plants back to a lush, dark green and restore their vigor. The analysis reads 3-0-0, with nitrogen supplied by calcium nitrate, magnesium nitrate and ammonium nitrate. Those same salts deliver calcium and magnesium alongside the nitrogen. Iron arrives as Fe EDTA, a chelated form that stays available in solution. Every source is water soluble, so the nutrients are ready for uptake as soon as they reach leaves or roots. Grotek aims it at yellowing seedlings and cuttings. It also helps plants stressed by under-feeding or transplanting until their vigor returns. Hydrofarm notes that it performs best as a foliar spray, indoors or outdoors. It also works as a root drench in soil, soilless mixes and water culture. This is a corrective supplement rather than a complete base nutrient. It sits alongside a regular feed program instead of replacing one. The concentrate is acidic, with a pH near 3.6, so it always goes into water before use.
Applying a Liquid Nitrogen Supplement as a Spray or Drench
Shake the bottle well before measuring. For a foliar mist, mix 10 ml per liter of water, about 2 teaspoons per quart. A wetting agent in the sprayer helps the solution spread across each leaf instead of beading up. Mist newly rooted cuttings and seedlings lightly and evenly. For root feeding in soil, soilless mixes or hydroponic reservoirs, mix 5 ml per liter, about 1 teaspoon per quart. Run a small test spray on a few leaves first and check them the next day before treating a whole crop. Apply when yellowing appears or when plants are coming through under-feeding or transplant stress. Once new growth comes in with healthy color, let the regular base program carry on. If yellowing keeps returning, check root zone pH and EC, since the cause may be uptake rather than supply. Rinse the sprayer after each use. Store the bottle in a cool, dark place with the cap tight.
