I agree with Posy and many plants can suffer from being what is known as 'checked' which happens if they are planted out too early and suffer from a cold period, lack of sunlight or drought/too much rain while they are young. Some of them recover but others never really get going again. If in doubt, keep them in modules/pots for another couple of weeks before planting out, or even make two sowings a couple of weeks apart if you have the space so that you can replace affected plants. Some of the most sensitive to this effect are capsicum, sweetcorn and beans but many veg can be affected. Successional sowing are your best defence but it does seem like a waste if you have a good year and nothing gets checked.
