Q: How should I use Essentials LAB 30% pH- to adjust the pH level of my nutrient solution? 
A: First, carefully check the pH of your nutrient solution. If the pH reading is too high, then the solution is not sufficiently acidic. Add a small, measured amount of Essentials LAB 30% pH- to your nutrient reservoir and mix thoroughly. Check the pH level again and note how much it has changed. You now know how much a certain dosage of Essentials LAB 30% pH- has lowered the pH in your reservoir, and from this you can judge how much more, if any, you need to add to achieve the desired pH level. 
Q: The pH level of my solution is already low. What should I do? 
A: If the pH is within the recommended range, you should do nothing. But if the pH is too low, then you should use Essentials LAB pH+ to adjust it to a higher level, within the recommended range.
