Looking good.. I wouldn't be too worried.
Possibly looking a little tired.. Wouldn't you be if you stayed up for 24hrs at a time?
I personally prefer 18/6, just seems a bit more natural and they seem to perk up after a bit of a sleep. I've seen em droop like that just after watering as well. I water twice a week at that stage depending on how quick your soil dries up. One of those waterings involves a half strengh fertilizer. I use a spray bottle to just moisten the top soil around the stem to ensure those little baby roots don't dry up too much.
Keep up the good work.
