Plant Problems

Hello all today i woke up and noticed these problems with 3 of my plants. Any ideas?? I usually have a good watering schedule but missed a couple days watering it, do u guys just think its underwatered? Will it go back to its natural self again?
Thanks

is tha whole plant like that or just those leaves

likes like simple wilting to me.

little more water and it should be fine

yea man it dont look bad at all. maybe it might not be enough like down there. or the plant looks pretty big and after a while the bottom leaves die off naturally

its either gettin under waterd or over watererd.iu should have to water every 2 to 3 days deppendin on pot size....
