If I pH down my water too much am I able to use pH up or is that bad practice? I know, bee careful in the first place but occasionally it happens to a nube 😆
Short answer, yes.
Long answer...as noted a little at a time is best until you know how much for your setup. Use a syringe or shot glass. I stick with cc/ml or cooking measurements but others use ppm and meters.
If you get your water ready the day before check ph. Then add nutes or epsom or whatever for that period. One at a time. Shake well after each addition. When done let sit an hour or so and ph again. If okay, 5.6 - 6.8 give or take, use as needed. If to high or low use what you have to correct.
Most nutrients I use raise ph so I can try adding rather than ph up but if I’m in a hurry a little ph up works fine.
I only mix up to 7.5L at a time. But always have at least two 7.5L containers and a 38L bucket full of 24hr old water handy.
Hope that’s not more info than you wanted. 👍😝
