Here is a recipe for small systems that supply tomatoes, peppers and leafy vegetables:
Ingredients
Base with micronutrients/trace elements: Masterblend 4-18-38 Hydroponic Fertilizer: this is still missing magnesium sulfate and calcium nitrate.
One kilo costs about 30 to 49 euros and is enough for about 1500 liters of nutrient solution
One kilo costs about 30 to 49 euros and is enough for about 1500 liters of nutrient solution
Magnesium sulfate: Epsom Salt
One kilo costs about 5 euros
Calcium nitrate: PowerGrow Calzium Nitrate 15.5-0-0
One kilo costs about 24 euros
Recipe
Mix the ingredients in the following ratios: (2:1:3). You must not mix all the ingredients together .
To do this, take two containers (bottles) of 500 ml each. This will prevent the calcium nitrate from reacting with the phosphate and precipitating.
Fill the first bottle with 120 grams of NPK fertilizer and 60 grams of magnesium sulfate. If you use warm water (preferably deionized or distilled), the components dissolve better. Remember that tap water already contains calcium and magnesium. Depending on the water hardness, you should reduce the amount of calcium and magnesium. One °dH corresponds to 10 mg CaO (calcium oxide) per liter of water.

Solution 1: mix with 500 ml water |
| 180 grams of calcium nitrate (about 3/4 cup) | Solution 2: mix with 500 ml water |
| Plant | concentration |
| Fruit-bearing bedding plants |
Solution 1: 3 ml per liter of water: for 10 liters take 30 ml, for 1 gallon = 12 ml
Solution 2: 3 ml per liter of water: for 10 liters take 30 ml, for 1 gallon = 12 ml

| Green leafy vegetables | Solution 1: 2.5 ml per liter of water: for 10 liters take 25 ml, for 1 gallon = 8 ml
Solution 2: 2.5 ml per liter of water: for 10 liters take 25 ml, for 1 gallon = 8 ml

When mixing the nutrients, pay attention to whether the plants show any signs of deficiency. Read more here: Signs of deficiency.
If you have an EC or TDS meter, the concentration should be between 1.5 and 2.0 EC. Read more here: EC and pH values of plants.

1 US gallon = 3.78541 liters = 231 cubic inches (inch³)
1 liter = 0.26417 US gallons
1 American gallon = 4 American quarts = 8 American pints = 3.785411784 liters
