scabby tomatoes

Can anyone tell me what has happened to my tomatoes please.  As you can see they look awful! I have them in a poly tunnel in bags.  I have watered them frequently and fed them fortnightly.  They are not all from the same plant. Many thanks.

    Can we have photos of the plants please?  My initial guess would be an extremely severe spider mite infestation.  If you can see any webbing on the growing points, that would be confirmation.  If no webbing, it could be thrips.
    A trowel in the hand is worth a thousand lost under a bush.

    Not entirely sure, but mould or fungal infection of some sort. Have you been keeping the poly well-ventilated and only watering at the base of the plants in the mornings to keep the plants and the air dry? If you over-water and/or allow the humidity to build up (often happens overnight when temps drop) you will have problems...
