Default calcium and acidity question

(zone 5)
i use vinegar in certain acid requiring plants' water (hibiscus, azalea) to
maintain (or get to) a pH 7

vinegar is not recommended, as it will decompose in the soil & may produce
compounds which are toxic to plants. I think you would do better to use
Miracid. City tap water in most locations has enough calcium for most plants.
The usual problem is too much.
