Offical HydroBuddy thread

Thought I’d ask here since I can’t figure it out myself, I used to use Jacks before and my pH settled at 5.8 and was stable.
Now the pH doesn’t come down to 5.8 and I have to use pH down and it keeps on drifiting up.

I run a DTW.

Any clues why that is happening?

I was looking to DiY my own hydro salt recipe as I don’t want to go back to adjusting pH before watering and I can’t automate it yet…any suggestions?
Ammonium Phosphate seems like the only acidic compound, anyone used Calcium acetate?
