It has nothing to do with the RO water; it has everything to do with the mix. 4.3 is pretty acidic; your babies won't like it. You may want to look for a better alternative.Good luck

Dont test runoff its not accurate and ph 3.5 soil just sounds weird, not sure any brands go that low even for acid loving plants. I think your over thinking it, at that ph the seeds will die or germinate then die quickly, if they dont die straight away your method of checking soil ph is bad wrong and making you overthink too much.

I filled solo cup with Amaerican seed company starter mix. holes in bottom of cup pored water through to get enough in a mason jar. Around 8oz. of run through. emersed ph probe, watched it drop. Or does the water hydrate the safe particulates that suspend the roots and result in a different p.h.? I/E..Potential Hydrogen vs. Available Oxygen..

Some ionic (probably organic too) elements are easily flushed and some are not in soil, all your doing is reading whats released and not the proper value of the soil.
Right but it gives you a pattern, PPM is important too. 0/low ppm water=ph dont matter
You dont need to ph in soil with healthy soil.
How are the seedlings doing?
I use a probe and during veg im mostly on 7.0.
This is the only probe i know that works, you have to keep it polished, make sure the soil is wet, compress the soil with a shot glass or something where you gonna probe, and spin the probe fast while you insert it.

Outdoors it helps me know if i gave it too much organic ferts granules (they all acidic AF)/organic liquid from alaska/kellog and if the soil is too hot (literally, seen warm temps lower ph).

There is no pattern to runoff you will be able to read and set your plants on. You may think but thats not how soil is used. A lab will be able to tell you everything but assure you they do not use the same methodology as you.

forget about the water run off. just concentrate on what's in your watering can. if the ph in your watering can is around 6.5 for soil and 5.8 for coco then you are fine
For areated ammended soil indoors 6.5 where you give 1ec liquid feed? or else there's no point for soil because my tap here is 500ppm mostly cal mag PH is 7.5ish and plants still grew green n healthy except for the bugs.

I only use run off as my second opinion. As long as it’s not way out of whack I don’t worry about it.

i just can't understand how his run off is PH 4.3 when it's going in at 7.0

Its soil, maybe bacterial biofilm test as low ph but dosent mean its absorbable by plants. Could be a million reasons but you shouldnt check it even if it is low it means nothing outside a lab.
