Why have my green peppers in the greenhouse developed a blackish "bloom" ?

Hi mad. there is nothing wrong with your peppers, they are ripening, after the blackish bloom they will turn red.

Hello Mad.

I grew chillies for the first time this year, and I noticed that they turned black. I thought they were diseased and was about to cut them off when a friend pointed out that this is what they do before turning red. They were Apaches - I'm just waiting for the the Pepperino's to do the same now!

I have some chillies, white going purple!
