Additional Information

To maximize plant growth, the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media-such as rockwool and gravel products-are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.

So far I've only had to use the ph down but a few drops per 1/2 gal!! This stuff works great will buy again.
It does what it needs to do using very very small amounts. I was in a hurry for some reason and didn't really take the time to measure the amount of solution I used to bring it down from 7.9 to 6.5 for a gallon of water but it was about half a teaspoon give or take? Give or take... Great product.
on time and as described
