My Home Guard first earlies have brown patches in the tubers. They have no
smell, and the potatoes are edible with the brown bits cut out. On the
outside they seem okay, until I start cutting them, (apart from some scab).

I am hoping it is not blight as the haulms seemed healthy, and I have read
that the tubers would be rotten and smelly, but I would be grateful for
ideas - could it be early blight? Actually- thinking about it - the first
plant I dug up did have blackening on the stem and one of the potatoes was
soft and smelled, but the rest have been as I have described

I have only one left to dig up now, but would be grateful for any help and
advice.

Thanks
