Pretty sure my tap water and previous grows done with mg ferts cause high build ups oil salt and calcium. What amendment can I use to help level things out I mixed rain water and some soil mixed for 5 min then drained water and tested it only dropped from 7.1-6.8 I read that’s how you can test soil ph without a probe. I plan to get a ppm pen but that’s gonna be a minute
