First Grow! Ethos, Purple City, Mephisto

Day 1: I planted all three seeds directly in soil, then kept them warm on top of the wireless router for about 8 hours because it gives off a ton of heat (let's not talk about humidity). But luckily Amazon delivered the humidity dome and heat mat today, a day early, so I transferred the seeds in there as soon as it arrived. Day 2: Since this is my first grow, of course I'm impatient, so I did something stupid and gently moved some dirt with a toothpick to see if the seeds were germinating yet. Of course they wouldn't be this soon. BUT TO MY SURPRISE... the Ethos and Mephisto had cracked and were starting to sprout. I tried to resist the urge to fiddle more, and just made sure the heat and humidity were high (probably too high). And I didn't resist the urge very well, but at least I tried. Day 3: Today all three seeds poked their little cotyledons out of the ground for me, within 48 hours of planting. By evening they were ~2 inches tall. Not bad so far. I had to gently remove the stuck seed casing from the Purple City sprout leaf—maybe that's why it was slightly behind the others? Day 4: I finally set up the grow tent, and moved the plants in there to get more consistent light than our windows offered. It took some time to get the environment dialed in, but eventually found an appropriate temp/humidity balance by putting on the humidity dome cover, but leaving it cracked open about an inch. I'm trying to maintain 70–80° and 60–70% RH. I think that's about right? Day 5: Nothing to report. Seedlings are growing! They look bright and healthy. Purple City is still lagging behind, but otherwise seems fine. Day 6: Did a lot of staring at the plants today, fiddling with their position and waiting for something to happen, ha. I finally removed the humidity dome tonight, and the environment is still maintaining a decent temp/humidity balance without it. They look healthy, as far as my novice eye can tell. I'm sure future me will look back on this and laugh at my naivete. Day 7: Purple City has caught up to the pack! Now the Ethos OG Kush is beginning to look like the runt of the litter. The soil seemed dry (not bone dry, but dry) and slightly separating from the pots, which I think is a sign of underwatering. And maybe it was my imagination, but the leaves also seemed a bit too dark, which I think is also a symptom of underwatering. So I soaked all 3. They just kept drinking it up, so I kept on watering, and probably ended up overwatering. But the peat pots drained a lot of excess water, so I think I'm ok. Still learning and paying close attention so I have a better idea of what's normal for next time. Day 7 part 2: Whelp, there goes my first mistake! The seedlings were stretching higher than it seemed like they should have been, so after a bunch of research it turned out the grow light was WAY too far away. (I had read that seedlings don’t need a ton of light, but maybe that’s outdoors?) I had the Ionboard S22 positioned 40” above the plants at a 30% intensity, but AC Infinity recommends 18” at 40% (or 36” at 100%). Either way, I was only giving my poor little girls a fraction of the light they wanted. So now it’s at 18”/40%, and hopefully we’ll be back on track soon.
