I think everything is correct upto bolded. I think he just suspected Nacho when nacho handed over the pills to the EMT. Then Victor tailed him and reported that he threw the pills in the river. That alone is enough.
Assuming all Nacho was doing was replacing his meds with placebo, there almost certainly nothing that anyone would be able to detect and/or put in any kind of report for Gus to find.
I mean if the writers explicitly made that part of the plot, I'd suspend my disbelief. But in the absence of that I'm going to go with reality.
