Veggi can you start from the beginning? Soil type etc? And then exactly what "you did to them" as specifically as you can.

You know I am FAR from a soil expert but it's better to be lucky than good so anyway so maybe I can help a little bit at least.......

If they got overheated you watered them right? And got them out of the sun and into the shade right?

And how much worse from two days ago do they look now?
