how to cure over fert

ok, I'm guessing this is right, I added some fert the other day.

3 out of 4 plants had fert.

The one that didnt: it's base leaves (the second set) that grew, died.

2 out of 3: the leaves are drooping more than anything, they are yellow, and one has dropped off. *Once again, the base leaves are*

the 3rd one that was ferted, which is also the smallest, seems fine and healthier than ever.

The weather has been swelteringly hot here, and they are high in humidity.

I don't know what the heck is going on, someone please help!!!
:( :( :( :(

with plain water, at least 3-4x the volume of the container....bonbon

Have you overwatered them??? It's a pretty common mistake. What are you growing in? Indoors or outdoors? Try to keep in mind, the the simplest solution that answers all the questions at hand is usually the right solution. If they are indoor or outdoors and the humidity is through the roof, make sure that you are not using more water than the roots can take. The high humidity will slow down the plants ability to move water and the soil's ability to evaporate water. Good luck!

has been high in humidity, but yellowing, drooping leaves?
Pretty certain its over fert. Problem is I dont make the soil unlike some people here, so I dunno whats in it....
might try hydro, i dunno....
