There are several reasons a plant can look like this - overwatering (the state of being constantly wet), underwatering and nitrogen toxicity. I'm going to rule out nitrogen here as your plants aren't dark green... and I'm going to rule out overwatering because the soil looks terribly dry. Culprit: you're not giving her enough water!
Give her a drink so that there is runoff and it collects in the saucer/tray underneath.... let the runoff sit there for a few minutes to see if the soil soaks it back up. If it does, give her more water... again wait to see if the soil soaks it back up.... keep doing this until no more runoff is being soaked back up into the pot and then throw the runoff away. This will ensure that all the soil is sufficiently moistened and the plant has what it needs to continue growing. Then wait until it's dry before giving her a watering with nutes... She's desperately, desperately thirsty!
Good luck..
