Essentials LAB pH Down is a concentrated acid (81% phosphoric acid). Used to adjust the pH of nutrient solutions. This pH is highly consentrated and a very small dose should be used to adjust your pH.
To note, when you are increasing your pH for example with 0.5ml intervals, the higher you go up the pH scale the quicker the same amount of solution is going to raise your pH. So if 0.5ml raised it by 0.2 pH it will not increase it the same amount the next time, so be cautious and keep testing your pH after each small amount of pH added.
This is because pH is logarithmic meaning that each integer increase or decrease results in a tenfold change in concentration. For example, a pH of 3 is ten times more acidic than a pH of 4. Similarly, a pH of 3 is one hundred times more acidic than a pH of 5.
Correcting pH is one of the most important phases of your plants life. A correct pH level helps plants absorb the maximum amount of nutrients. pH influences the solubility of nutrients and chemicals in soil water, thereby determining the amount of nutrients accessible to plants. Your plant will intake different amount of nutrients at each level of pH so for best results we reccomend to go between 5.5-6.5 to capture each available nutrient.
Most of these plant nutrients get caught in the range between pH 5-7, this is why we recommend sticking to 5.5-6.5 as this will alow most of the nutrients to abosrb into your plant.
Your pH levels may differ depending on what water you have. For soft water the same amount of pH solution will adjust it differently to the same amount in hard water. You need to check first what water you have, this is done with an EC pen. Or check this zoned map of what water you might have in your area.
This is not a completely accurate map, to fully know what water you have you can check with an EC pen.
