Cannabis enjoys 500-600 ppm after cloning, 800-900 ppm when vegetating, and 1000-1100 ppm when flowering. So knowing the mineral content of your water before mixing your nutes can avoid stressing you and your plants.

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 is the best EC for marijuana?
The perfect EC value is different for each cannabis strain. In general heavy-feeding indicas prefer higher EC values of 2.5+, while some light-feeding sativas prefer a low EC of 1.0 or they will become over fertilised. Water has an EC value of 0 and usually is pH neutral so 7.0 pH value.
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 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.
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 happens if EC is too high?
Excessively high EC levels lead to stunted growth, leaf damage and eventually plant death.
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 do I lower my tap water ppm?
High PPM Hard Water There is no easy way to deal with hard water. One cheap option is to use a basic water filter. You will have to replace the filters often, and not all the dissolved minerals may be removed effectively. Reverse osmosis filters can do a much better job at reducing dissolved mineral particles in water.
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.
Why are my buds so small?
Overcrowding or Overshading An overcrowded grow room, poor spacing between plants, or bushy vegetative growth—due to the lack of pruning or training—can reduce the amount of light that a plant’s bud sites get, affecting bud growth and size.
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 is a good PPM for water?
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.
How is quality PPM calculated?
PPM (Parts per million) is a measurement used today by many customers to measure quality performance. To calculate: For example, let’s say you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000=. 025 X 1,000,000 = 25,000 PPM.
What is the normal PPM of tap water?
The typical sample of tap water in the U.S. contains approximately 350 parts per million (ppm) of TDS, which does not on its own indicate a health concern. However, lead concentration is found 1000 times lower at the parts per billion (ppb) level and is too small to be detected without sophisticated instrumentation.
