Why are my seedlings dying?

I’ve killed three seedlings so far. Basically what happens is the plant looks good for a few days, then falls over and shrivels up.

First of all, could the tap water Ph or ppm be so bad that it’s killing the seedling? I haven’t yet bought a Ph meter (I know, stupid. But I am overwhelmed deciding what kind to buy, any recommendations are welcome).

This last time I let the seed germinate for a couple days. It had cracked a little and the stem was barely showing when I planted it, about half an inch deep in a 50/50 soil/perlite mix. The soil is some very cheap Scotts stuff that has no nutrients, so it shouldn’t be nute burn. Immediately after planting I watered it and put it under 18/6 light cycle.

At first I thought the soil was too hard but that doesn’t seem to be the problem, as this time the soil is quite aerated.

Am I using enough light for a seedling? I have two 27 watt 6500 k daylight bulbs in a y socket, screwed into a metal reflector thingy I bought from home depot. I have this situated such that just one of the bulbs is giving most of the light. the one light is pretty much horizontal and directly over the plant, about an inch and a half away.

Maybe I’m watering wrong? Basically I poured tap water that had sat out for about 48 hours. I poured the water until it started dripping out the bottom of the container. My container is a ziplock plastic food dish with holes drilled in the bottom.

Is it okay to pour some of the water directly on the still-underground seedling when I watered? cause that’s what I did.

Sorry lots of questions, but could somebody give me an idea of what I’m doing wrong?
