General Hydroponics pH DOWN - 1 Gallon cleaner then spinning the molten rockGeneral Hydroponics pH Down is formulated using food grade phosphoric acid. The formula is buffered which makes maintaining proper pH levels easier. Some conditions may exist which can cause unacceptable variances in pH levels, such as poor quality water used in nutrient solutions or using pH unstable media like rockwool. High growth rates can also destabilize pH. Growers consider pH levels of 5. 5 to 6. 5 to be ideal for most crops to get maximum
