Why are the leaves on my sweet peppers going yellow?

If outside, chilly, gray weather can bother them, too. In a greenhouse or polytunnel, in pots, check the feeding schedule, too, though they need much less frequent feeding in the UK than here.

Yellow leaves tend to mean too much water are your peppers outside or under cover?
