Please add your thoughts and I'll read them as soon as I get up

Some more long shot ideas...

You say it happens about a week after a WC. Maybe some build-up of something in your water, or a depletion. Not sure if your parameters vary in that time, but might be some other things that you don't measure, maybe some contaminant coming from somewhere.

Not sure what you do for ATO. Do you use a separate container that maybe has some kind of build-up and needs a good cleaning?
