What pH and ppm of your source water and do you adjust to before watering the plants?
I find that peat moss and specifically Pro Mix HP is nearly pH neutral medium with its ability to buffer pH fluctuations as nutrients are absorbed from the saturated medium.
Do you flush the peat moss grow medium between grows and re use the grow medium? If so, how many grows can a single bale of peat moss be reused for without issue?
If you require a wetting agent to aid in reducing the surface permeability of the peat moss ivory soap may be used.
Part of the complexity is that the grow nutrient manufacturers use different chemical formulations which change every time per batch and the chemical stability and compatibly is only within their product line.
The few times I did test, the pH from the tap was under 7 and then after mixing with Mega Crop it would stabilize around 5.8. And while that's just me getting lucky that my water and nutes jam so well, the buffer in the soil matters more than than what's going in. Think we're in agreement here.
I feel like pH meters are one of those things that get recommended to people first starting that they probably don't need. Another is Lux meters for people with a single light. If the manufacturer is any good, you should be able to trust par maps and hanging recommendations. Cool that we can check with phones now though.
I don't flush the soil before reusing it. Water only for a bit and light nutes at first.
Haven't had issues really but probably because most of the MC gets used up.
Could see the soil being hot still in some cases. Thanks for the soap suggestion.
I only reuse twice then compost, but some others mentioned just reamending. (lime, yucca, myco...)

@Zembretti, that peach stuff sounds sweet.
I switched to grove bags for storage. They do a decent enough job for me to not go back to jars.
Have stuff that's still terpy after a year or more in the bag. No need for bovedas either.
I prefer to treat them like jars though and burp my way down instead of trying to dry perfectly before bagging.
