The comment about lime added to Jiffy peat caused me to do a wee experiment.

To water from my RO-storage tank, I added one Jiffy pellet. The water Ph was
about 6.6 in the beginning -- about right for RO exposed to air long enough
to get some CO2 dissolved. After soaking the pellet an hour or two, the pH
had dropped steadily to about 5.5. After boiling and cooling, it was still
around 5.5.

It convinced me no lime was added, but now I realize you were talking about
Jiffy Mix and not the pellets. :-) Oh well. It was something I should have
checked a long time ago.
