Achieve the perfect pH
To maximize plant growth, the pH level 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. pH can acidify to an unacceptable level when nutrient solutions are used with poor quality water, or pH unstable media, such as rockwool. High growth rates can also destabilize pH.
Use sparingly - add to nutrient solution, a little a time, then test pH. Repeat application, then test, until desired pH is achieved. The quantity necessary for pH adjustment will vary depending on the strength of the nutrient and the purity of the water used to mix nutrient.
This product raises nutrient pH. Recommended pH for most plants is 5.5 to 6.5.
