Given the containers size(since you aren’t taking much space) you could try and revive but looks pretty far gone. Not that I would personally know, but from everything read, overwatering signs. I went with FFOF for mine and did straight to soil germination in it. Watered the day of planting and waited until the pot felt light (I suppose you could always use a small scale at the beginning if you don’t trust your gauging the weight) and added in 2.5-5 mL of water(days 3-10 from putting seed in soil) when they were feeling light. Otherwise only wetted the domes (zip-lock bags) when I saw they were getting a little low on the moisture drops clinging to the sides(most say common practice of twice daily but I think there could be quite a few factors involved in determining that, air flow under the edges of your “dome”, dryness of the soil in the container, RH of room depending on your “dome”). I have been using straight from tap that comes out 6.6-.7 consistently and it has a ppm of 300. But remember, different strains could yield different results from one person to the next depending on a lot of factors. Feel free to check out mine as they have been progressing and I’m on day 18 today, or 19 when I turn the lights back on in 3 hours. I’m doing Bergman’s Gold Leaf and Sour Diesel auto strains from ILGM.
