Why pH Down - Citric Acid
- Citric acid is an organic acid that can be used to lower the pH of a solution or soil
- Has been shown to reduce powdery mildew occurrence when used as a foliar spray (Jadari et al., 2012)
- Reduces leaf yellowing caused by iron deficiencies by aiding in iron uptake (Pierre et al., 2000)
Ingredients
100% Citric acid derived from non-GMO cane sugar
How to Use
Soil & hydroponic: Dilute in water then mix to desired pH
Foliar spray: To create a 0.1% solution, add 4g to 1 gallon of water or 240mg Citric acid per cup of water
