Your opinion is noted … however the water used
still would not make much of a difference in a “ prebuffered “ or ready amended medium. Distilled is a source best saved for steam irons and baby bottles- seriously. Tap water - under most circumstances - is good enough as your outside shrubs / grass / mangy cats still drink. You shower it and brush your teeth in it. So why should not be good enough for
any plant ?
Once again … its the medium. The dead giveaway is that OP mentioned he might have to give it nutes. If that soil was “ already amended properly or RTU ready to use “
it would be feeding it .
Big difference in RTU medium then what is in that seedling’s container.
