To understand the nutrient concentration of your soil, you’ll want to test both the pH and PPM or EC of your runoff.
|Vegetative Stage||850 – 900 ppm||1,8 – 1,9|
|Flowering Stage||900 – 950 ppm||1,9 – 2|
|Flowering Stage||950 – 1050 ppm||2 – 2,2|
|Flowering Stage||1050 – 1100 ppm||2,2 – 2,3|

What should my PPM be during flowering?
Early Flowering: 950 to 1000 PPM — As your plants grow, they need to eat more. PPM readings will reflect the particles in the increased nutrients. Mid-Stage Flowering: 1000 to 1100 PPM — Your plants’ nutrient intake continues to increase at this stage.
What should my hydroponic ppm Be?
As plants consume nutrients and water, the nutrient strength in the hydroponic reservoir will change. GENERALLY, nutrient strength should run between 800 to 1500 parts per million (ppm).
What should the TDS be for hydroponics?
The ideal TDS reading for plants grown hydroponically varies from around 500 or 600 on up to well over 1,000. That said, we suggest sticking with a TDS level of around 800. Leafy greens, like lettuce and spinach, for example, require a TDS level of around 550 to 850, much lower than the 1,200-plus that bok-choy needs.
Should you remove fan leaves during flowering?
Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.
What is a good ppm?
However; with the passage of time, the expectations increased to 1,000 PPM and now, the expected PPM rate, especially in the manufacturing industry across the globe, is around 75 PPM. One PPM defectives mean one defect, error, or event in one million.
How many ppm should my water be?
According to the EPA secondary drinking water regulations, 500 ppm is the recommended maximum amount of TDS for your drinking water. Any measurement higher than 1000 ppm is an unsafe level of TDS. If the level exceeds 2000 ppm, then a filtration system may be unable to properly filter TDS.
Why Does My ppm keep rising?
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.
What is the difference between ppm 500 and ppm 700?
What’s the difference between ppm500 and ppm700 scale? The ppm 700 scale is based on measuring the KCl or potassium chloride content of a solution. The ppm 500 is based on measuring the NaCl or sodium chloride content of a solution. The ppm 500 scale is also referred to as TDS – total dissolved solids.
What ppm is good for plants?
Levels between 30 and 60 ppm are considered optimum for most plants. Irrigation water tests should always include both pH and alkalinity tests.
What is a good EC reading in hydroponics?
For most hydroponic crops, the ideal range of EC for most crops is between 1.5 and 2.5 dS/m. A higher EC could prevent the plant from absorbing nutrients due to increased (more negative) osmotic pressure, and EC levels that are too low could adversely impact yield.
Does ppm matter in hydroponics?
For a clear picture of how much nutrients your plants are getting, you need to measure the PPM or EC of both your nutrient solution/reservoir (if you’re using hydroponics) and your runoff. If your PPM/EC readings are super low in your runoff, it’s a sign you need to up your nutrients.
