General Hydroponics pH Down Liquid commercial nutrients and other equipmentThe Acid formulation uses food grade Phosphoric acid to lower the pH to the proper level. To maximize plant growth, the pH 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.
