help seedling not looking good

so it had roots out the bottom of rot wool this is a dwc for fun but don't wanna waste it transplated it last night only 6 hours light time now in dark will start light again soon doing 18/6 . water line is just to the bottom of the basket rockwill is very wet but top hyroton isn't wet . ph 6.1 water temp 66 76 room temp

Rock wool might be water logged. Try lowering the water level so the bubbles are splashing the bottom, not submerging it. Can't really tell from the picture since its not focused.

Seedlings usually stall because of too much moisture...let em get bigger before putting them in..better success rate ime..try gently squeezing some water from the cube, put in warm environment..imo 5.8 would make it happier than 6.2
Good luck hope you can save her

Thanks guys, i took it out of the dwc and just letting it air dry and do it own thing, looking little better
