Nutrients

Nutrient solutions should include nitrogen, phosphate, and potash.

Nitrogen

Nitrogen gives plants the energy that they need to grow.

Phosphate

Phosphorus Deficiency

You can tell if there is a phosphorus deficiency by looking at your plants. If there is a deficiency, the plants will look small and are producing little or no flowers.

Excess Phosphorous

This is unlikely because plants have a hard time absorbing phosphorus. Phosphorus is vital for plant growth.

Potash

Potash improves water retention, taste, and color. It can also help improve the plant’s resistance to disease. Potash should not be added to the solution when sodium chloride is already present.

Adjusting pH

pH adjustments should be tested on a single plant before you make changes to the entire system.

Lower pH

Add small amounts of distilled white vinegar.

Increase pH

Add sodium hydroxide or potassium hydroxide to the water.

pH can also be adjusted by using pH up or pH down, which can be purchased online
