I ended up taking the 3-toed leaves off all the closet plants. Most were laying on the soil or near it and would have to go soon anyway. One thing I have started doing is weighing my little pots. It really keeps from overwatering the seedlings. I got a little flat-top kitchen scale cheap that goes up to 11lbs.
While I lifted the little pots and they seemed fine, weighing them told me different, and since it was day two in tiny pots there's no worries about overwatering. The easiest thing for me is to get one plant well watered. Soak it and let it drain all that it's going to then weigh that. Then the other 11 plants take no time whatsoever. I can water them to that weight and move on to the next one. They are in individual trays, so if some drained out it will likely get absorbed into the pot within an hour. If not I'll dump the trays, but so far it works like a champ.
And there's no waiting on the first one after you get a pot/plant size figured out. Those little 1/2g pots with soil, a 4" plant and a hydrofarm tray weigh 850g when soaked. As the plants get bigger it goes up by whatever the plant weight is, but you just need to get close.
The pots were down to the 600g range which is light enough to add more. They got topped up to 950g with a full dose of coconut water, and after inspecting each plant I'll be punching the timer buttons when i hit "post reply". Flipping at 4 weeks for all but the SWxP which is at 6 weeks.
This lot is twice the plants that the just-flipped ones were. Everything in the early flower tent had lanky structure, no branching, and basically a lot less bio-mass. This group seems to have made up for that. If they get close to needing water after a day I'll stick them in one gallons while waiting on them to show rather than stressing them out.
