Brassica problems

[wilko]

:) hi,
I was wondering if anyone could tell me what is wrong (if anything!) with my PSB, and cabbages, never grown anything to eat before, but these yellowing spots concern me,

Do they want feeding maybe!

can't see any critters ( although I didn't have my specs o   ::))

the leaves on the PSB also look 'curly ' is this normal?

the cabbage by the way is savoy ( I know that should look crinkly  ;))
