Chilli plants problem....help!

[northepaul]

Hi all
I have several varieties of chillis - all have been going great guns with loads of chillis.
I noticed when my chocolate habanero was about 6ins hight its leaves were all crinkly, but thought that maybe this variety had leaves like that, so didnt think any more about it. Whether its related or not, the leaves on my other ones has started going brown and falling off, along with some chillis too
My Prairie Fire also now has crinkly leaves at the top....??

Any advice to save them, I dont want to loose all my chilli plants.
Pics attached.
(PS its not leaf scortch as I always water from the bottom)

It may seem a simple question, but are you watering enough? and a picture of the full plant will help.

Where are they kept? I hadmine in the conservatory and the flowers just kept falling off them I have now put them outside and the flowers are setting the heat through glass was a bit to strong.
