Two seedlings, two problems :(

Well guys, I’m not sure what’s going on...I recently had a pH issue that has since been corrected, upgraded from a grow box to a grow tent to prevent pests, changed all of my soil and pots out, wiped the tent and room down, treated new pots with a misting of Neem oil prior to use...

Somehow, it appears as though I have a fungus on one seedling along with some other bad looking stuff, and one seedling turning extra dark toward the center of leaves..

at this stage in their life should I perhaps begin watering more than just a misting, and keeping the top soil dry?

they are both on Day 8

Strain: Forgotten Cookies x Forum Stomper by Mephisto Genetics (auto/feminized)

Age: 8 days

Soil: Fox Farm Happy Frog, Fox Farm Ocean Forest, Perlite (40/40/20)

Light schedule: 20/4, 17.5” height from pots, Mars Hydro TS-1000

Feed: just misting pH 6.5, dechlorinated tap water

Environment: 3x2x5 apollo horticulture grow tent with AC Infinity Cloudline S4 in-line duct fan for exhaust, a Honeywell fan on the floor and a clip on Vivosun fan just above the lights, but angled to blow air around the outside edge of the interior of the tent.

stays around 80°F, 45-55% humidity.

Any help at all is appreciated guys, thank you! My first grow ever actually went 100% perfect, so this is so nerve wracking!!

also included photos of the entire tent setup, airflow directionality, etc.

should I open more than one passive intake flap?

Get the jars off the seedlings. You don't need a dome for starting seeds.

Get the soil more wet and get a fan on them. Make them dance in the breeze.

Done - to both of ya - thank you for that tip! I just saw a thread the other day on here before registering where someone said, “you wanna simulate natural wind, not a hurricane”, so I was worried about too much lmfao!

Got movement on all of them! Should I throw the dome back on the unsprouted one, or just keep it moist-er?

and for the comment about wetting the soil more — I actually just did, but laid down fresh DE, and lightly turned, so it looks a little drier than it is on camera!

edit: added a small step-up for the Honeywell fan to get the air flowing straight across the top!

Well, the situation just worsened overnight for one of them. For the other, it is doing okay. Very brittle leaves, so much so when just wiping one, it tore as you can see. Doesn’t seem to be bugs. I’ve used Neem Oil on all leaves, upper and under side, of all plants in rotation, and the condition on this one still worsened severely..

is this potentially damping off or a fungal infection? I just spotted a fungus gnat, a single one. I’m just so confused...i thought upgrading to an enclosed environment from a space bucket would actually be worth it lol! I’m getting it dialed in slowly...
