the plant looks fine overall, but it does appear to be over-watered.

the grey does look like residue from being foliar sprayed. you can start watering as soon as the plant has roots (which it obvoiusly does).

it's not uncommom for plants to sag when the lights go out, by the way.

and you want girls, not guys, so you might want to consider new names. lol.

good growing!
