Using lemon juice for lowering Ph of water

[JimG]

I am starting to use Super Soil Concentrate. I want to use filtered lemon juice to lower the water Ph. I would appreciate any insights.

Thanks

I use lemon juice for just that. I dilute it 50/50 with water and store it that way. It is probably a better idea to dilute it even further prior to adding it to your nute solution but I typically don't bother.

You need to test its compatibility with your nutrients and other additives using the water you normally use. Do that by mixing up a feed solution and storing it at room temperature at the medium pH for your growing medium. Measure pH after 15 minutes of rest.

Measure any changes in pH each day and also smell it for any odour build up. If it holds steady for a week without odour it will work perfectly fine.

I grow in coco. No issues.
