Dunno, written words can be tricky.
I was jus' explainin' for everyone ...
It's not like drenches are expensive, either. This measuring subject comes up a lot, so we keep trying to find new ways to say it. If we want to soak/dunk, we need more fluid - need something for the last couple plants to sit in and soak up. So that means more water, and if we want to keep the drench/water ratio right, that means more drench, too ... so that ends up being more drench per soil gallon ... it can be confusing, but it doesn't need to.
Hence my post. Use as much water as you want.
The pot will only soak up so much, anyway. If you're gonna dunk, then you'll need more, and you'll have to toss some. It's not expensive.
I'm the same way - a habitual conserver. I save twist ties, for pete's sake. So I get it. But it's not expensive, so ... *shrug*
But the easiest way to measure for 1-2 plants at a time is to put as much water as you'll need in a pail and then add the right amount of drench and Tea. I mix those into solo cups with water. I'll end up running 8 plants with three different drenches, so I'll put 3 measures into one cup, 2 measures into a different cup, and maybe 2 measures in a third (the others might just be straight water or 1/4 Trans). The Tea goes into a separate cup. Then I fill a pail with enough water, pour the appropriate solo cup in there and drench the first plants, then do the second batch, third batch etc, and I got into the habit of doing Tea all at once - simpler that way - just use 16oz of water for each plant that will get it, mix in the Tea, and pour a cupful into each pot.
Two measures - how much water and how much drench (and Tea).
[Edit] Forgot - it hasn't been mentioned in awhile, but you can't get the measure "wrong". It's not close to being an exact thing. The only trouble is if you're off by like 10x.
Consistently, for several times. Plops usually work just as well. That's annoying but true. Leaf damage comes from screwy soil chemistry, not because of an "overdose" - it'd be more like a misdose. Foliars are another matter - you can overdose those.
