Boca Hydro Chelated Manganese EDTA 14%

Boca Hydro Chelated Manganese EDTA 14% is a high-purity, fully water-soluble micronutrient fertilizer designed to correct and prevent manganese deficiencies quickly and effectively. Manganese is an essential element that supports photosynthesis, chlorophyll formation, enzyme activation, and overall plant growth.

Our EDTA-chelated formula ensures maximum stability and uptake across a wide pH range, making it ideal for hydroponics, coco, rockwool, soil-based gardening, fertigation, foliar feeding, and container plants. The 14% fully chelated manganese delivers fast, reliable results without precipitation or nutrient lockout.

Key Benefits

14% Fully Chelated Manganese (EDTA) for maximum uptake and stability
Corrects and prevents manganese deficiencies rapidly
Essential for photosynthesis, chlorophyll production, and enzyme activation
Fully water-soluble — dissolves cleanly and mixes easily
Compatible with hydroponics, soil, pots, containers, foliar sprays, and fertigation
Professional-grade quality trusted by growers and greenhouses

Symptoms

Symptoms of manganese deficiency include: Leaves turning pale green between the veins, and possibly brown and die. In citrus, little leaf cannot be corrected with manganese. Manganese deficiency can lead to significant yield loss.

Plants generally push magnesium to new growth and old leaves develop pale green color, with manganese it is the opposite.

Chelation prevents reactions with other nutrients and enhances the absorption and utilization of rate in all plants.

Boca Hydro Chelated Manganese Dosing PDF

(1 g = 50 ppm Mn)

Stock Solution
Dissolve 100 grams (3.53 oz) of Boca Hydro Chelated Manganese EDTA 14%
in 1 gallon of distilled water
1 fl oz (29.57 mL) = 0.78 grams of dry product
1 fl oz = 109 ppm Mn

Foliar
Use 0.25–0.5 grams per gallon
Use 1–2 tsp per gallon of concentrate
(5–10 mL of concentrate = 13–26 ppm Mn)

Pots and Containers
Small pots: 0.05–0.1 g/gal (1–2 mL per gallon concentrate)
Large pots: 0.1–0.25 g/gal (2.5–6 mL per gallon concentrate)

Drench (5 gallons of water)
Maintenance Feeding: 0.25–0.5 grams (5–10 mL or 1-2 tsp concentrate per 5 gallons)
Defeciency Correction: 1–2 grams (20–40 mL or 1.3-2.7 tbsp per 5 gallons)

Hydroponics
Target: 2-5 ppm (mn/Gal) of manganese. Do not exceed 5ppm
2.5 ppm Mn 0.70 grams of Boca Hydro Chelated Manganese EDTA 14% per gallon
5 ppm Mn = 1.35 grams of Boca Hydro Chelated Manganese EDTA 14% per gallon

Start at 2–3 ppm Mn (0.5–0.8 g/gal) for general use or regular feeding.

Use 4–5 ppm Mn (1.0–1.35 g/gal) if plants show signs of deficiency such as interveinal chlorosis on younger leaves, or if you are feeding citrus.

Manganese is consumed regularly, a top up of 1/4 gram per gallon per week is sufficient for established plants.

Fertigation

Target Mn in Irrigation	Product per Gallon of Stock (1:100)
2 ppm Mn	21.5 grams (0.76 oz)
3 ppm Mn	32.2 grams (1.13 oz)
4 ppm Mn	43.0 grams (1.52 oz)
5 ppm Mn	53.7 grams (1.89 oz)

Example:
Dissolve 53.7 g (1.89 oz) of Boca Hydro Chelated Manganese 14% in 1 gallon of water.
Inject at 1:100 to deliver 5ppm Mn in irrigation water.

To make 10 Gallons of 100x stock solution ( For injectors set at 1:100 dilution):

Target Mn (ppm in irrigation)	Grams of Product	Ounces of Product
2 ppm	215 g	7.58 oz
3 ppm	322 g	11.36 oz
4 ppm	430 g	15.15 oz
5 ppm	537 g	18.93 oz

Additional 5ppm MN injection rates

Injector Ratio	To Achieve 5 ppm Mn: Use…
1:100	53.7 g per gallon of stock (1.89 oz)
1:200	107.4 g per gallon (3.78 oz)
1:500	268.5 g per gallon (9.47 oz)

Frequency: Every 7-14 days during active growth or as deficiencies are identified.
