Something is munching my Brocolli plants both those bought as plants and those I have grown from seeds. Doesn’t seem to be slugs, cant see any tiny eggs or caterpillars although there are small tracks on the reverse of larger leaves? Might it be Vine Weevel although there are lots of big bits from the edges of leaves as well as the middle? The photos below give you a better idea, some of the larger plants have had whole leaves devoured while others have survived attacks, my seedlings are coming on and it looks like they will be victims as well 🙁
