What does a PPM meter do?

The measurement is commonly used to describe the concentration of something in water or soil. TDS meters give readings as ppm (parts per million). In the metric system, ppm is easy to figure out because the readings are equal to 1 gram in 1,000 liters of water, or 1 milligram in 1 liter of water.
Keeping this in view, what happens when ppm is too high?
Adding a normal amount of nutrients makes ppm too high: This means you're probably using water that had high ppm before the nutrients. Try using nutrients made for “hard water”(water with a high concentration of minerals), such as Flora Micro Hard Water. This will lower the overall ppm.
Also to know, what is the best ppm for hydroponics?
Week | ppm range | EC Range |
---|---|---|
Week 2 | 600–1000 | 1.2–2 |
Week 3 | 800–1200 | 1.6–2.4 |
Week 4 | 800–1200 | 1.6–2.4 |
Week 5 | 800–1200 | 1.6–2.4 |
The ppm of the nutrient and water solution in the reservoir rises as you add more fertilizer to the hydroponics system. Topping off the reservoir as the water evaporates may lead to higher ppm of fertilizer salts, which can damage your plants.
