Could use better instructions, but product does lower the Ph of your solution. Use sparingly. Make sure to test your water Ph to get it right. It is a fair value.

I grow some dedicated plants and flowers in my yard. If you are doing the same I would recommend to use this ph lower solution. It helps to lower the ph ultimately preserving nutrition and helping better growth for your plant.
