Grains/gallon can be thought of as an "American degree". It's a hair
smaller than the German degrees that we use more often. Rather than
confusing things with more sorts of degrees it's probably better to
stick with reporting results in mg/l.

Looks fine to me.

You don't need to, and it probably won't do your plants any good. But
feel free; experiment away and let us now what happens :).
