Lights out leaves down?

I know this is gonna sound like an idiotic question and that I have no common sense, however I can't seem to find a definitive yes or no answer anywhere. I just put my plants into flower a few days ago so I've just been paying a little more attention when the lights are off now to make sure my timers work(or make sure I didn't screw them up)and I noticed the leaves are drooping when the lights are off.. I'm assuming this is normal as long as when the lights are on that the plants look healthy and green right? Just want to make sure in case something is wrong which I'm pretty sure there isn't. Thanks y'all
 
I only water them when the lights are off I don't stand in there and have parties. I just happened to notice it is all. When I go in the room to water I use a red or green light to see. This is probably why I can't find a definitive answer

You don't want to water your plants at/during ights out. A little after the lights come on, is when you want to water.

IDK man even in a pitch black sealed room sometimes my ladies pray at night and my co2 levels drop as low as 56 PPM without the burner running, as its lights on only. It really depends on the plant I think. In veg I notice a lot of drooping after 18 hours but sometimes I can go into my room and my plants aren't laying out even when its been pitch black for 4 hours.
'
To be fair I do have a 1/4 size veg room attached to the same building. Its possible the veg plants are consuming the co2 but the levels never drop as much as they do at night when the flower room shuts off .

Here’s my plagiarized response:
Yes. Cannabis plants, like most plants, take in water through their roots, use that water in a variety of chemical reactions, and exhale the byproducts (namely oxygen as O2) through microscopic holes in their leaves called stomata.
During the day these stomata open to allow respiration to occur. If the plant can take in slightly more water through its roots than it can breathe out through its leaves the plant becomes turgid, or filled with water to the point that it becomes stiff. This is because osmosis is ultimately driven by evaporation.
Think of the plant as a drinking straw filled with liquid. At the top of the plant there is a device that allows the water to evaporate without losing the negative internal pressure inside the straw that is drawing the liquid up. As the liquid evaporates, more is drawn through the straw. This is the process plants use to supply themselves with water. It is a physical, mechanical process that, once set in motion, will not stop without intervention, although it can be regulated by the plant through a variety of methods.
Turgidity in plants is a great indicator of a plant's health. Unhealthy plants often have a very hard time maintaining this ratio. If the air is too dry and water evaporates too quickly for the roots to keep up plants will close their stomata to slow down the rate of evaporation in an effort to maintain turgidity. If the air becomes even drier the plants will begin to wilt as gases leave the plant faster than it can replace them with liquids.
At night the plants have no reason to respire. There is no sunlight to drive the processes that require respiration, so the plant essentially closes shop. Its stomata shut almost entirely to preserve water and its roots cease to uptake water and nutrients because the driving force (evaporation) can no longer coax these resources up the stalk. Since it can't do real work at night, the plant uses this time to rest. It is akin to sleep in that the plant is able to repair itself from the work done during the day. Some physiological process do proceed. Some water and nutrients continue to be used at a much slower rate than during the day.
Because the plant is still using water and nutrients, some byproducts get exhaled through the almost-totally-closed stomata and cannot be replaced through osmosis as they would during the day. This means that the water holding the leaves in a “praying" position during the day gets depleted, causing the plant's internal turgidity to drop and in turn causing the leaves to droop.
It is normal and healthy for this cycle to continue in this way through the life of the plant. Drooping at night is expected, but if the plants start dropping during the day it is likely an early indicator that they aren't growing at optimal efficiency and the growing environment or soil nutrients could be less than ideal

I thought it was normal I just wanted to make sure.. I'll post pics later tonight.. I built a 4x8 room(roughly)with a converted refrigerator to store the mother and the other side of the room is where the plants are.. over the plants I put sheet metal with the lights under that. On top of the sheet metal I made another box for clones. Some people like clones some don't so I'll see what happens. I've heard reasons for not liking clones which most make sense but others don't so I figure I'll try and see how it goes.. thanks for the answer I appreciate it
 
Oh
You don't want to water your plants at/during ights out. A little after the lights come on, is when you want to water.
Oh.. I think I read something about not watering in the sun at least not in the blazing sun and it was better to water at dark so the plants aren't getting burnt kinda.. I guess I just figured not to water with the lights on. I've been watering them the whole time with the lights on but I just put them to flower and I know things change during that stage so figured I'd water at night. I'm new to this so I'll take all the advice I can. A friend of mine used to grow a LOT and he's helped me some kinda but hands on and learning from mistakes is how I learn.. he told me about vic highs soil mix and I got parts I could and kinda pieced something together it seems to work so far.. I'll get better once I kinda figure out the routine hopefully. Appreciate the advice
