cal or mag def flush out your soil make sure ph is correct and dont use any nutes untill back to normal
your soil was probably to hot...burned them leaves up a little. pull and plant in some coco/per lite till she recovers, then transplant her back add a buffer soil mix between roots and your mix.
it is simple. And if you cant take such actions from fear of stress and death...then you my concerned friend need to up your skill level. To each his own, flushing would be the last thing i do at this point.
