My pH is too High

[Hanna]

Based on our experience with other growers, some will add small amounts of sulfuric or phosphoric acid to bring their pH down. Vinegar might work but it is not a strong acid.

When using your pH meter, make sure you calibrate it and store the electrode in some electrode storage solution. It will maintain it's integrity over a longer period.

I am using General Hydroponics pH Down product and it is working really well. I do kep my pH meter in a solution as u sugested. Thanks for the advice , really appreciate it. Since I have brought my pH down, my lettuce is thriving, seems like lettuce likes the pH between 5-6. But my spinach seems to like pH around 6. I have learned so much doing this.
