Save your roots by changing the water and flushing the roots with 35% food-grade hydrogen peroxide solution. But it's important to note that not all hydroponic systems can be saved.
After treatment, supply more oxygen to the root system. The best way is to provide air pumps and air stones to your hydroponic system.
Provide good drainage to your hydroponic plants by using LECA or perlite. Don't overuse absorbent media like peat moss and coco coir. Unwanted pathogens thrive in moist conditions.
Change your hydroponic nutrient solution regularly. The plants ' roots will use up all the nutrients in the hydroponic system and cause nutrient imbalance.
Maintain a slightly acidic pH level for the root zone and prevent bad bacteria that thrive in neutral to alkaline solutions.
Maintain a cool water temperature. High temperatures at the root zone reduce the amount of oxygen the water can hold.
Wash your hands before and after working with your plants – it’s one of the easiest ways to prevent the spread of bacteria.
Assist hydroponic roots by supplying beneficial bacteria. There are many available commercial probiotic formulas to support the root zone.
