RO Water

@Medicated Bonsai i tested my ro water at the sink and I was correct on what I remembered. It came in at 9.3 on both my blue lab pens and in the 9’s using drops. Ppm was 20.

That's almost exactly what I got haha. I wonder why i'm getting 9's on my pH pen and 7's on the drops. Btw, does GH pH up down liquids hurt the plant? Seems like pretty toxic stuff.

Haha sorry fellas, this is kinda confusing for me. So, is it bad to use RO water with no nutrients? Should I mix some calmag and mega crop before I feed then? And do I still not pH after adding this stuff, since i'm growing in soil?
