2.) If you are using nutrients and still seeing nutrient deficiencies , the first thing to do is check is the pH of the water going in, and the runoff water coming out. This is because the wrong pH can prevent plant roots from absorbing nutrients effectively

All testers come with step-by-step directions that tell you exactly what you need to do to make sure you pH tester is accurate for years to come.

Water

Why is it a good idea to let the pH cover a range instead of always adjusting to the exact same pH number? Some nutrients are better absorbed at slightly higher pH readings, while others are absorbed better at lower pH readings. Not having to try to pinpoint an exact number also saves a lot of unnecessary frustration.

Lime is one of the most proven ways to bring up the pH of soil outdoors.

But if you’re just thinking about buying standard potting soil from the local garden store, or using the soil you found around your house, you’re probably going to need liquid nutrients to supplement your cannabis grow for the best results and yields. Maintaining pH is one of the best tools you have to get the most from your nutrients.

A lot of growers don’t have the time or space to mix up their own soil, which may involve amending, understanding how micro-organisms in the soil affect nutrient absorption, maintaining a compost pile, etc. Because growing in soil can involve a lot of prep work (or for those who live in a city where there’s not enough room for an organic, composted soil grow), there are hundreds of liquid nutrients which can be much more convenient for cannabis gardeners.

The pH scale — which ranges from zero to 14.0 — provides insight into how chemical compounds will interact with one another based on their ionic state. It is good to remember, pH reflects the concentration of hydrogen ions in a solution. More intuitively however, pH from a practical sense can be understood in terms of acids (vinegar, ammoniacal nitrogen) and alkaline bases (baking soda, potassium bicarbonate).

On the pH scale, values less than 7.0 indicate acidity; values greater than 7.0 indicate alkalinity. Deionized water has a neutral pH of 7.0. The pH scale is a logarithmic function, so even small changes in pH values are significant. For example, a pH level of 4.0 is ten times as acidic as a pH level of 5.0. For plants, pH is important because it affects the form of the nutrients in the substrate.

Caption: Nutrient availability increases or decreases in response to pH. A pH level of 5.8 – 6.2 is appropriate for cannabis.
