In the first pic, do you see how the top leaves are kind of droopy? They still have some health left but they're arched and not flat. That resembles an over watering condition may have happened recently (but not definitively). The leaves on the bottom of the plant appear to have no life left . They just fall straight down, parallel with the main stalk of the plant. That's an indication of under watering. The second plant shows signs of the same thing. The third looks like it's fared a bit better.
So they're definitely thirsty, but may or may not have had an over watering situation in the recent past.
Are you in soil or peat? 6.5 pH for soil, 6.0 for peat (Promix, Sunshine #4 etc)
