Have you been watering them over head?

[Blackbob]

bit more info regards how long they have been planted out and what size they are at would help.
mildew problem seems likely with what you have said up to now.

Dear Bren, if you look on the underside of the leaves, you may find clusters of grey aphids.....these can cause the leaves to pucker and also be the cause of the pale patches. If it is these and there and are not too many, you can just go along and squash them with your fingers or thumb.

Hi Blackbob they were planted on the 10th May, the cabbages have started to heart up and the sprouts are quiet sturdy, yes I have watered them from the top but if it rained it would be from the top.

OH as you said a lot of grey aphids on the curled leaves, not too many I did squash them with gloved fingers.

Thank you both
