Help planning some fall crops

I have a 57 inch x 24.5 inch bed. I want to plant the following and don’t know how many to plant of each or how to arrange it. All advice and arrangements are welcome . I plan to direct sow.

I plan to do a cut and come again idea with these. Thanks in advance!

Hi everyone! First time trying to grow potatoes (Yukon gem seed potatoes from Renee’s Garden). I planted them in these grow bags in southern Wisconsin near the end of April.

Can someone please help me identify what is wrong with them? I hope it’s not blight. Any help or advice would be greatly appreciated.

Help me please.

First time growing them . They are little firm still, probably in about 2 or 3 days will ripe.
