Those are beautiful girls for sure. They are very hungry and 1.2L won’t keep them wet long enough. Are they in soil or coco? Feed 1.2L twice a day and see what happens. See if they don’t droop. Maybe 1.2L when you wake. 6hr later lift them and see if they’re somewhat light. If that’s the case they’re flying through your water and that’s a good thing! Just means you have to feed them more. I’ve had this happen to me with a plant. She’d be happy all day until I fed her. Few hrs before lights out and shed droop as if she’s was over or underwatered. She eventually came out of it. I use coco but definitely do what I suggested bro. If she’s lightish 6hr later just feed her again
