...tucking isn't behind this drooping, it's likely it a water issue,...ironically, both over- and under-watering will cause the drooping,... from what you wrote, under-watering seems more likely,.. problem is, if the soil gets to dry, sometimes it can be a bit difficult to rehydrate evenly, making for dry-ish patches within the pot,.... As Derek mentioned, hefting the pots is a good way to tell if they're properly moist, but you need have some "calibration" first, to get a feel for what a well watered and dry pot feel like,... using a wetting agent will help greatly when trying to get dry soil evenly moistened,...
