1st grow, did I screw up these seedlings?

You'll have to get that RH up at some point.
I would start addressing that before the plants outgrow their dome... which they're gunning for already.
IME, critical RH swings are usually more detrimental to a plant than suboptimal seedling RH. From dome to tent, you're looking at halving your RH ... that's a big swing.

Thanks!
That's valuable information (the RH swing vs the RH at the moment).
I'll probably leave the cover/dome on for a few more days (keeping the RH high inside); and maybe get a small humidifier to raise the RH outside the whole tent, then remove the dome and have the controller remove, say, 5% RH each day.

Which RH would you say is good for this species to settle on inside the tent when I transplant it into a pot? (photoperiodic White Widow)

I use very similar punnets and once they are around your age i up pot into a little bigger pot and bury half of the stem..up potting will also bring up the rh a little too..

Wellcome back @ComfortablyNumb

60% is a good target range throughout. Early veg, you could go around 70%; late flower around 50%

They've only been there for 5 days. Do you reckon it's safe to up pot them now?

These are mine when I replanted, they where about a week old. They should be just fine

5 days later

They won't need the massive humidity they have in the dome once they are planted. They will start adding to it on their own.
Transpiration. Plants breathe out O2 and water.
