  • Follow the directions that come with the meter to calibrate it.
  • Please wait until the meter’s reading is stable after you put it in the nutrient solution sample. Then, take note of what the meter shows.

Use the up-and-down methods to change

Based on the first reading, determine if you need to increase or decrease the amount.

When the pH is too low (acid),

  • Start by adding some Up solutions to the nutrient solution.
  • After stirring it, let it move around for a few minutes.
  • Use a test kit or meter to check the amount again.
  • Add the Up Solvent in small amounts until you reach your desired range.

When the pH is too high (alkaline)

  • Mix a small amount of the Down solution with the nutrient solution.
  • Allow it some time to move around.
  • Use a test kit or meter to recheck the pH level.
  • Mixing up solvent in small amounts will help you reach the desired range.

Adjustments and checks regularly

  • After changing the pH, keep an eye on it to ensure it stays in the proper range.
  • Perform a test at least once a day or more often if necessary.
  • If the pH falls short of or exceeds the optimal range, repeat adding the solvent (up or down) slowly until it’s back to where it should be.

Taking care of and cleaning the meters (if needed)

  • If you use a meter, follow the instructions to keep it in proper shape and clean it.
  • Use the correction solutions that come with the meter to ensure its accuracy. Also, regularly adjusting the meter will help maintain its accuracy.
  • After each use, clean the electrode with distilled water and put it away as the maker suggests.

Following these steps, you can use the kit to measure and change the pH levels in your hydroponic system.

How to Control Hydroponic pH

Here are some tips to keep your hydroponic garden under control and get the most nutrients:

Understanding what causes change is essential:

Water quality: The starting level of your nutrient solution depends on the water source’s pH. Before adding nutrients, you should test the water to see if it already has any differences.

Nutrient solution composition: The amounts can change depending on how the nutrients are mixed. Therefore, be aware of how your nutrients might affect the required amount, and make changes as needed.

Plant species: Different plants have different pH levels. Find out what level your plants need and change your nutrient solution to meet those needs.

Every day: Regular monitoring is essential to catching changes early. At least once a day, ideally simultaneously, check your nutrient solution’s pH to ensure it stays the same.

Change pH in small steps: Change pH gradually. It lets you fine-tune the level without moving outside your desired range.

If you are using a recirculating hydroponic system, test the waste’s pH periodically to ensure it is in the correct range. If necessary, change the nutrient solution.

Reliable readings require pH buffers and calibration solutions.

Set meters straight: To get exact readings and avoid mistakes, calibrate your meter regularly using the calibration methods it comes with.

Use buffers: pH buffers are solutions with known values that can be used to adjust and check measuring tools’ accuracy. Use a buffer to check your meter or test kit periodically.

Keep the General Hydroponics pH Control Kit safe and use it.

How to store solutions: Follow the manufacturer’s directions on managing up-and-down solvents. If not, storing the solvent can reduce its efficiency.

Keep things clean: Keep the kit’s parts clean and free of anything that could dirty them. Additionally, rinse meters or probes with distilled water after each use to prevent dust buildup.

During the different growth stages, monitor things and make changes as needed. 

Your plants may need different pH levels during different growth stages. Find out what each phase (e.g., growing and flowering) needs, and make the changes you need for the most effective growth and development.

With these tips, your system will help plants better take in and use nutrients. Moreover, managing pH in your hydroponic garden will work well if you check it often, make small changes, and pay attention to the plants and the water.

A Quick Fix for Every Common pH Issue

Hydroponics depends on keeping pH in the proper range. But these problems can sometimes happen. Here are some of the most common problems with this system and possible ways to fix them:

Too high (alkaline): 

Cause: Too much Up solution or alkaline water.


  • Add small amounts of a down-solvent to the nutrient mix to slowly lower the pH.
  • To lower the pH of the nutrient mix, use filtered or reverse osmosis (RO) water.
  • Also, change the makeup of the nutrient solution to lower alkalinity.

Too low (acidic).

Cause: Too much use of down solutions or an acidic water source.


  • Add small amounts of Up solution to the feed to raise the pH slowly.
  • To raise the pH, use alkaline water sources or change the makeup of the nutrient solution.
  • Also, look for root rot or a lack of nutrients, which can cause acidity, and fix those problems.

Changes in pH and instability

Cause: The nutrient solution isn’t moving around well enough because it isn’t mixed well enough.


  • Improve the hydroponic system’s air flow and movement to help the nutrient solution mix better.
  • Ensure pumps, air stones, or other devices that move air work well.
  • Also, look for clogged water lines or other things that prevent nutrients from reaching the plants and fix them.

Possible reasons and ways to fix each problem

Nutrient imbalances: Imbalances in the concentrations of nutrients can impact pH. Change the amount and type of nutrients in a nutrient mix based on what the plant needs.

Organic decomposition: Acidification occurs when organic matter breaks down. Regularly clean and change natural media like coconut coir or rock wool to prevent acid buildup.

Unwanted changes: Changes that aren’t right can cause pH changes. So, making changes slowly and in small steps is essential while closely monitoring the level.

More tools and methods for controlling pH

pH buffers help prevent the nutrient solution from becoming more or less acidic or alkaline. You can add them to the mix to maintain the same range.

Some helpful bacteria and fungi can help keep the pH stable by controlling nutrients and promoting a healthy root zone. Therefore, adding microbial inoculants or using amendments high in microorganisms can improve stability.

Automatic systems for monitoring and controlling

pH controllers are electronic gadgets that simplify tracking and changing the level. They consist of a pH probe, a controlling unit, and a dosing pump.

The probe constantly checks the level; then, the processor turns on the dosing pump to add Up or Down solutions and keep the level in the desired range.

Based on your set parameters, pH dosing devices automatically add adjustment solutions to the nutrient solution. They remove the need to make changes by hand and let you monitor and control things in real-time.

Different goods and ways to adjust

  • Natural options for down solutions include citric acid or white vinegar. These things are acidic and can help reduce the amount. However, it would help to be careful when using them because their strength and efficiency vary.
  • In organic hydroponics, biodynamic products like BD 506 (valerian flower tea) are sometimes used to help plants grow naturally. These mixtures are made from certain plants and minerals and can help gently and long-lastingly keep pH levels in a healthy range.
