don't know where your at
but keep his in mind, clover after a few frost or colder temps will pucker up[ and NOT be much of a draw to deer
the turnips/brassicia will actually be mostly bitter till they GET a few frosts on them, , the frost/cold tempos tend to change the chemical structure of them and makes them sweeter for deer and things to eat them
soybeans> they draw deer when green leaves, and then when dry
at my farm I can loose an acres of beans in about 2 weeks or less, it will be picked clean(lots of deer there though)
so, pending here your at, keep this stuff in mind, as different temps and times of yr, is when things draw deer best
clover will be the stuff they maybe hit first on you, as won't be long and it won;'t be much to draw them at all!
next will be beans and sunflower seeds IMO
and turnips and brassicia's last?

a week before season would be maybe where I would open them up at
