High values help cation uptake and low values help anion uptake: every fixed pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eUsers of T.A. \/ General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because the 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch1\u003eHow to use\u003c\/h1\u003e\n\u003cp\u003e\u003cstrong\u003eTo adjust pH:\u003c\/strong\u003e Add a small amount to water or nutritive solution as required.
