You can easily lower EC by diluting your system with fresh water. Take measurements intermittently while adding water until it is mixed to the correction level. You can raise EC by adding fertilizer.

How do you control EC in hydroponics?
To reduce the EC value, clean water is added to the water tank. To increase the EC value, nutrients are added to the water tank. If the EC value of water rises during time, it is a sign that plants are unable to use nutrients in water. This may be due to the wrong nutrients or wrong pH value of the water.
What happens if EC is too high in hydroponics?
A higher EC means higher salt concentration, while a lower EC means a lower salt concentration. Excessively high levels of nutrients induce osmotic stress, ion toxicity and nutrient imbalance, while excessively low values are mostly accompanied by nutrient deficiencies and decreasing plant growth.
How do you regulate EC?
There are a number of elements that can alter the EC values: The pH, the mineral salt concentration, the oxygen purity and the temperature of the nutrient solution. This directly stimulates its aeration determining the nutrient uptake capacity of the plants, which will be higher or lower accordingly.
What should the EC be for hydroponics in US CM?
Typical EC values for hydroponic nutrient solutions can range from 500 to 2000 µS/cm, or 0.5 to 2 mS/cm. TDS measurements can be expressed in units of parts per million (ppm) or parts per thousand (ppt).
How do you test for EC in hydroponics?
How to measure EC? The easiest way is by using a digital meter, such as the Bluelab CF Truncheon. These work by measuring the electrical conductivity via the electrodes on the bottom of the meter. All you need to do is dip the end into your solution and check the digital reading.
Does pH down raise EC?
pH goes up, EC goes down = Plants are feeding. Potentially raise nutrient levels. pH goes down, EC goes up = Plants are putting nutrient into the water rather than taking them out. The reason this is ideal is that the plants are able to take up specific nutrients more efficiently at different pH levels.
Is EC the same as PPM?
Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for electrical conductivity, which is a measurement of the ability of something to conduct electricity. In horticulture, EC is the most accurate way to measure nutrient concentration in solution.
How does EC affect plant growth?
In general, higher EC hinders nutrient uptake by increasing the osmotic pressure of the nutrient solution, wastes nutrients, and the increases discharged of nutrients into the environment, resulting in environmental pollution. Lower EC may severely affect plant health and yield [2, 9].
Is EC the same as TDS?
Total Dissolved Solids (TDS) and Electrical Conductivity (EC) are two separate parameters. TDS, in layman’s terms, is the combined total of solids dissolved in water. EC is the ability of something to conduct electricity (in this case, water’s ability to conduct electricity). That’s TDS!
How do you convert uS cm to EC?
Often the literature will use microSiemens (uS/cm) and EC standing for electrical conductivity. These two units are the same. To convert milliSiemens (mS) to EC’s or uS multiply the reading by 1000. The meter in the diagram shows 1.65 mS which is 1650 uS or EC’s.
What should the EC be for soil?
Optimal EC levels in the soil therefore range from 110-570 milliSiemens per meter (mS/m). Too low EC levels indicate low available nutrients, and too high EC levels indicate an excess of nutrients.
