Hey guys, I got most of my brassicas out 2 two 3 weeks ago. However I planted some late this year. A few of the ones I planted late (last week) I see most of the leaves cleanly tore off, very clean looking. I have pictures below of one that has been striped of its leaves and one that hasn't. Anyone know what this is and how I can stop it? Thanks.
They seem to go only for the newer leaves...
