What pH Value Is Best For Weed Plants?
The optimum pH level range for weed plants growing in soil or coco coir is 6.0 to 6.5. Hydroponic cannabis grows set ups should stay within a pH range of 5.5 and 6.5.

What Is pH?
Potential Hydrogen (pH) is a measurement that gauges the degree of alkalinity and acidity of a solution. Derived from logarithms, it goes from 0-14 with the middle ground of 7. Anything lower than 7 is acidic, while anything above 7 is alkali. The midpoint, 7, measures as neutral. Water has a pH level of 7, which makes it neutral. Slight changes in pH levels could cause noticeable changes in a plant’s growth.
Recommended pH Levels Per Growing Medium
1. Soil pH Chart: 6.0-7.0
There is no “best” pH level for soil setups. However, the ideal pH level should fall between the 6.0-7.0 bracket. There will be instances where the substrate of your plants would measure 6.2. After watering, the level spikes to 6.6 in an instant. Soil is also a move forgiving medium in terms of pH level. It can support pH level fluctuations from time to time. But then again, continue to monitor pH levels and keep them at the right level.
2. Hydroponics and Soilless pH Chart: 5.5 to 6.5
A soilless growing setup could not only mean a water setup. It also includes coco soil as a soilless medium. Soilless structures require a different pH level. However, same as soil growing medium, this setup also allows minor fluctuations in pH levels since it also has an allowable window for changes. Hydroponics and soilless setups pose a greater risk in pH level fluctuations as nutrients require direct administering in the root base.
Why Is pH Value Important For Plants?
Remember that the pH level is a gauge if the plant absorbs the nutrients you are feeding it. A change in pH level alerts you that the plant is not absorbing the nutrients. Since specific nutrients fall either on the acidic or the basic level, it’s easy to monitor nutrient deficiency in plants if you can monitor pH levels.
Of course, the earlier you get to detect the nutrient deficiency in plants makes it easier for you to correct it. Monitoring pH values ensures that your plants grow healthy and free from sicknesses.
The Effects Of pH Levels In Weed
Potential Hydrogen (pH) in plants is a gauge that monitors how well nutrient uptake is going. Much like humans, plants require a specific level of pH for them to grow. pH levels can be acidic, alkali, and neutral. Depending on pH level, plants absorb an exact nutrient.
In some instances, if pH levels are at the extremes, it might cause problems in the long run. For example, if the soil is too acidic, there could be an increase in toxic elements. Plant production and water use will decrease along with the availability of essential nutrients. Meanwhile, if pH levels become too basic, it could affect metallic nutrients such as iron, zinc, and manganese.
Imbalances in pH levels can cause sickness in plants. Iron chlorosis, or the yellowing of leaves, is one sign that the pH level is too alkaline. If the setup is too acidic, plants could suffer from stunting and might affect them in reaching their full potential.
What Are The Benefits Of Maintaining The Perfect pH Value?
Keeping the pH levels at an optimum level will help the plants grow healthy and vigorous. When it’s time for harvest, a well-kept pH in plants is an assurance that there will be a good yield waiting for you. You can also avoid nutrient deficiency in plants at an early stage by maintaining an acceptable pH value.
What Happens If There Is An Imbalanced pH Level?
One of the causes of nutrient deficiency is an imbalance in pH value. But what’s surprising about nutrient deficiency is that it’s easy to detect. Regular testing on the growing medium could save you a lot of time and energy than resolving the lack of nutrients later on.
What Is Nutrient Lockout?
Nutrient lockout, or nutrient lock, as others call it, happens when your plants can’t absorb the nutrients given to them. Oversaturation of nutrients in the soil and an imbalance in pH level causes this phenomenon. If you fail to identify your plants are going through a nutrient lockout, there is a big chance that your plants will die. It’s good to know how to identify nutrient lockout in its early stages for you to reverse the effects or prevent it from happening altogether.
How To Test pH Levels In Plants?
Doing regular pH level testing prevents the development of sicknesses and nutrient deficiencies in plants. There are methods to choose from, like Digital pH Level Testers and Perfect pH Drops.
Digital pH testers are a quick and easy way to test out a solution’s acidity and alkalinity. After calibration, a digital pH tester will work wonders every time. On the other hand, pH tester drops require more effort. It needs you to color-match results with a color-coded list to know at which pH level your solution is. Test drops are also more sensitive than digital testers as they react to the simplest things like oxygen. One wrong move and the readings become inaccurate.

How To Correct pH Levels For Plants?
In case all steps to preventing pH imbalance fail, there are solutions to put it right where it needs to be. Household products, like vinegar and baking soda, are quick fixes that balance everything back to optimum levels.
If the soil gets too basic, lemon and vinegar could help you out. All you need to do is dilute a part of lemon or vinegar into 5-10 parts of water. Water the solution in your soil gradually and continue to test it out until the alkalinity lowers down to the desired range. But if your plants are in a hydroponic setup, using pH down is a better way to resolve alkali issues as it would be safer for the plants in soilless structures.
If your soil becomes too acidic, liquid dolomite lime product could help raise its pH level. For a quick fix, if it is not available, using baking soda could alleviate the situation. However, this is a first-aid solution. If you get the chance to use liquid dolomite lime products, do so. For hydroponics, using a natural pH solution is the best solution for acidic pH levels.
