I still do it wrong previously because I might make it too dry.
I haven’t seen any photos of dry soil yet.
Don't be so robotic in the math. You're looking for a fairly wide and forgivable range so a little over or a little under won't be the straw that breaks the camel's back. That said, let's estimate that 65 grams for both pots is done dry and 170 grams for total saturation. Water again when each pot is in the 80-100 gram window. For whatever reason you may wish to water at 70 grams or maybe 110 grams and that's fine too, but more or less, I think your ideal window is 80-100 grams to water again.
