Potatoes leaves dying yet never flowered

[queequay]

Help!! I am new to potato growing.
I have 3 types all growing in potato buckets the leaves on the Duke of York turned quite yellow and witled (i thought due to weather being so hot )
Now my Vivaldi are looking wilted and have some brownish spots. Worried its Blight but not sure.
I dug up one vivaldi and its looks a nice wee potato. The DOY are still tiny. Do i dig them all up to save the from blight or leave them a bit yet?? I just dont know what to do!!
Thanks

Some varieties don't flower.
The hot dry weather will see off some of your plants, and drought will give you tiny spuds, as will growing in buckets

You can leave them in the pot a few weeks until you need them, or until the weather turns cold & wet, whichever is sooner. Or until the slugs find them!
