I have been trying to grow some roccoto chillies  and while one of the plants was going quite well. However after three months of growing I got hit with a thrip infestation and 3 of my 4 plants died.

The 4th plant was surviving quite well,   it even had a flower 

when suddenly for no apparent reason it stareted dying 

After another day it looked like this 

So prune back the dead leaves is all I can do however it is now starting to show signs of new growth
