If you leave your pots in standing water and there is excess food in the water, I have found that it will burn the shit outta them... But that plant looks like it just needs to be watered
If you dont stop overwatering they will all wither up and die just like that one. Water only when pots are very light to lift, not daily ,every 2nd day etc.
The plant/pot tells you when to water, you dont tell it.
