Newly transplanted into rock wool 6x6s drooping leaves. Over watering? Under watering ? Shock?

Transplanted purple punch and 24k gold into the rock wool 6x6 cubes and today they seem to be drooping. Watered twice with clone x solution also put some clone x rooting gel on plug before putting into 6x6. Help!

Same thing happened to my plant after transplanting so I put in the shade and it bounced back in an hour or so, tried the sun again but it started to droop again. Think I’ll leave in the shade for a day or 2 and see what happens.
