Hesi pH - Minus Growth

Hesi pH - Minus Growth is a compound with nitric acid that allows you to raise the pH level of the fertilizing water so that your plants can assimilate the all the nutrients without any problem. You’ll ensure that your plants assimilate the optimal amounts thanks to the precise control and correction of this important parameter.

Marijuana plants start having trouble assimilating the chemical elements present in the growing medium when the pH level goes up or down too much. They absorb all nutrients between pH 5.3 and 6.5. Above and below those values, the assimilation curve drops drastically. That’s why most growers control this parameter before fertilizing their plants.

Hesi pH - Minus Growth contains only nitric acid so that when added to the fertilizing mix, besides correcting the pH, it adds a small amount of nitrogen that your plants will absorb immediately. This way, you won’t add harmful mineral salts to your plants.

Dose and usage of Hesi pH - Minus Growth:

• First add the fertilizers to the irrigation water.
• Measure the pH level, it should be around 5.5 - 5.8 during the growth stage.
• Add Hesi pH - Minus Growth little by little, stirring the water and re-measuring the pH until the appropriate level is reached.

Repeat each step until the pH is at the desired level. You can use Hesi pH + Plus to compensate if you go too low. We recommend adding a few drops at a time to avoid raising the EC level too much.

Composition of Hesi pH - Minus Growth:

38% Nitric Acid
