Cannabis really appreciates a wet, dry cycle.. When my ladies are in veg I find once every 3 - 4 days is enough.. as they get bigger I give them more each sitting but still try to keep it spaced out. The plant itself can take quite a bit of abuse and don't forget that the roots grow to seek out water. Healthy root structure is important to growth. I'm far from an expert but judging by your pics I'd say that they're grown from seed? and that they can't be more then 3 - 5 weeks old. In my experience at that stage of growth depending on the size of the pot, temp and humidity in the room, watering twice a week is more then enough.
In the future to avoid all the questions on the part of the people who are going to attempt to offer their opinions and advice you need to give up all the details right off the hop. For example Age? from seed or clone? Nutes or no nutes? Type of light? Temps? Water schedule? size of your grow chamber, size of pot etc. All of these seemingly miniscule details have an effect on your plants. when you start a thread by asking, "My plants are drooping is it from under or over watering? Plz and thank u " no ones going to be able to help without more details.. just a future heads up..
If you have been watering daily I say let her dry out, don't water for the next three days. Then water, not to the point where the soil is completely saturated but rather until you see a decent amount of run off.. stop there, repeat 2 - 3 days later... again this depends on all those little juicy details that you have left out..
I hope this helps.. feel free to ask if you have more questions.. Most of us are hear to help.. I dunno about this hot shot guy though lol.. haha j/k he knows his stuff I can vouch for him, GL.
