Beginner Gardening: Colocasia Leaves Flopping/Laying Down, 4 by SavvyDaze

My Colocasia Black Beauty & Blue Gecko had been growing just fine since April. Yesterday, in the bed on the south side, one of the newest, big leaves and some of the tiniest, emerging leaves on the Black Beauty flopped. However, the other Black Beauty two feet away was fine. In the backyard, east side, some of my Colocasia Blue Gecko did the same thing, yet the Mojito & Black Coral right next to it are fine. Both Colocasia were fine and upright all day. I left the house around 2pm and got home around 7pm and found these leaves flopping. Once it got dark and they didn't perk back up, I watered them, but they are still laying down/flopping this morning. Any idea what might be going on?

Thanks!
