Pepper and Chilli problems

I haven't had problems with my Peppers and Chillies before

These are photos of 2 of my grafted peppers and i have a couple of Chillies that look the same - they are all different varieties

How often are you watering?

I thought I was only watering when the plants needed it

Well, the pale green/yellow can mean nitrogen deficiency but I'm sure you're feeding them and the foliage is lush anyway. Let the mix dry out completely before watering again and see what happens.

Will do Italophile - thankyou

my peppers have given up... the leaves all looked curled up.. there were some flowers and teeny tiny peppers but they look all shrivelled up too... is this a bug problem please?

Sounds drastic. Any chance of a photo?

when you stop feeding your peppers and chillies

Peppers and chillies don't need a lot of feeding anyway. They're like tomatoes, much more likely to produce well if left to struggle a little. But to answer the question, once fruit is starting to ripen it's not drawing much from the plant and fertiliser is pretty much wasted.
