I was checking my new potato plants and found brown spots on leaves, I think it is early blight. So I dug some up most potatoes are fine put some have what looks like blisters on them, are these still ok to Eat. Thanks
I doubt if the blisters are blight. Blight rots the potatoes, and it's early for this to have happened yet. The blisters are probably a bit of scab, which is usually just superficial. If you can scrape or brush the potatoes clean, they'll be fine.
