It gets watered everyday, doubt it just needs water.....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
What this man says...... Learn the weight of an almost dry pot. Exercise those roots and get em chasing water. gauging water needs on the soil on the top of your pot is much less reliable, the top can be dry and be soaked underneath. The more you practice the weight thing the better you become. I can pick up my pots in the morning and pretty much know how long I have got to get em watered again. That said, the little fuckers are walloping 2L each per day 3 week into fower.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.
