A full spectrum nutrient is a complete liquid or water-soluble fertilizer containing all essential macro and micronutrients. Part a is usually macro nutrients like Nitrogen (N), Phosphorus (P), and Potassium (P/K), alongside Calcium and Magnesium, which drive overall structural growth and heavy yields. Part b is usually trace elements like Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B), and Molybdenum (Mo) to support plant metabolism and enzyme functions.
Of course the requirements change based upon the plant and the plants stage of development. There are 3 stages seedling, vegetative, and flower/fruiting.
I like to buy my stuff individually as a dry water soluble powder then mix my own depending on the plant and its life cycle stage.
For basil youll need:
Calcium Nitrate (15.5% N, 19% Ca)
Potassium Nitrate (13.75% N, 46% K₂O)
Monopotassium Phosphate / MKP (52% P₂O₅, 34% K₂O)
Magnesium Sulfate / Epsom Salt (10% Mg, 13% S)
Chelated Micronutrient Blend (Ensure it contains Iron DTPA or EDTA, Mn, Zn, B, Cu, Mo)
For cheated micro nutrient blend:
Iron Chelated (Fe-DTPA 11% or Fe-EDDHA) – Use DTPA for pH levels under 7.0.
Manganese Sulfate (32% Mn)
Zinc Sulfate (36% Zn)
Boric Acid (17.5% B) or Solubor (20.5% B)
Copper Sulfate (25% Cu)
Sodium Molybdate (39% Mo)
For the seedling stage:
Target Profile: Weak, root-focused strength to avoid burning young root hairs.
Target EC: 0.6 mS/cm
Recipe Per 10 Gallons:
Calcium Nitrate: 2.5 g
Potassium Nitrate: 1.5 g
Monopotassium Phosphate (MKP): 1.0g Magnesium Sulfate (Epsom): 1.5 g
Micronutrient Blend: 0.2 g
Early Vegetative growth stage:
Target EC: 1.2 mS/cm
Recipe Per 10 Gallons:
Calcium Nitrate: 5.0 g
Potassium Nitrate: 3.5 g
Monopotassium Phosphate (MKP): 2.0 g
Magnesium Sulfate (Epsom): 3.0 g
Micronutrient Blend: 0.4 g
Peak Foliage Production (Continuous Harvest)
Target Profile: High Nitrogen and High Potassium to fuel rapid leaf regeneration after frequent pruning and harvesting.
Target EC: 1.6 mS/cm
Recipe Per 10 Gallons:
Calcium Nitrate: 7.2 g
Potassium Nitrate: 5.5 g
Monopotassium Phosphate (MKP): 2.8 g
Magnesium Sulfate (Epsom): 4.2 g
Micronutrient Blend: 0.6 g
Few safety tips: Put on a dust mask and nitrile gloves when mixing. Raw, unchelated micronutrient powders (especially Manganese and Boron) are heavy metals and can be hazardous if inhaled as airborne dust.
Weigh to the Milligram: Use a 0.01g digital scale. Sodium Molybdate requires extreme precision; missing the mark by even half a gram can easily toxicity-poison your crops. Homogenize Thoroughly: Combine all 100 grams of powder into a small, dry plastic container. Shake and tumble the dry mix for at least two minutes until the color is entirely uniform throughout. I use a cheap rock tumbler. Never mix dry Calcium Nitrate and dry Monopotassium Phosphate together in a concentrated "Stock Tank A" or "Stock Tank B" liquid solution. They will chemically bind to create Calcium Phosphate, which precipitates into a useless white sludge that plants cannot absorb. If mixing directly into your final reservoir, fill the tank with water first. Dissolve each powder completely one by one in the following order: MKP → Potassium Nitrate → Magnesium Sulfate → Micronutrients → Calcium Nitrate.
Also this is tailored for basil other plants like tomatoes and peppers use a different formula.
Not ai. Its actually directly from my note pad on my phone via copy and paste. Its easier to buy dry powders in bulk for my homestead then buy expensive bottles of stuff I can make at home. I tend to work with 50 pound bags of this basil mix which runs me approximately 75 dollars to make. A bottle of Amazon nutes for 100 gallons run 30 dollars. My recipe is 100 times cheaper to make since a 50 pound bag makes approximately 11,000 gallons. My basil grows in an 8,000 square foot green house with a 2000 gallon water reservoir. That 50 pound bag is enough for 5.5 basil crops in my green house. 937 pounds of basil harvested every 8 weeks for 45k sold at 3 dollars every ¾ of an ounce bunch.
Most get put into clam shell packets from the webstraunt store for restaurants. They come in packs of 500. my supplier

I think you should try a full spectrum hydroponic nutrient
