So I top watered my seedlings today and runoff water looked odd. It was a yellowish, ale color. I took a reading on a TDS meter and it read 82 ppm. I don't know why it's like this, as I only water them with distilled water.
I believe this is an issue that I have run into several times before without realizing. A lot of seedlings I've had always seemed to have died off for no reason.
I think what's happening is that the peat/perlite mix I use for seedlings seems to break down and release stuff into the water, causing the ppm in the soil to raise to a deadly amount. But this is only a hypothesis.
I've drained the soil multiple times to get it down to below 30 ppm since then. But does anyone have an ideas of what could be happening?
