Looks like 3 quarts added on April 26 and 2 quarts added on May 1.It will go away, but jacks is ambiguous about how long it lasts and it would also depend on the dosage that was applied. Since you’re unsure of the dose as the PB applied it, your guess is as good as mine.
On May 2 they note that sequesterant level was tested at 12. Nothing was added after that point
