What's wrong with tomato leaves?

Help please, my tomato plants were doing well but the lower leaves have recently gradually turned yellow between the veins, curled inwards and some are now developing brown blotches too- see photos.  Fruit is setting ok so far.  I am feeding once a week with tomorite, and watering nearly every day, as soon as soil surface has dried.
Is this likely to be a watering or feeding problem, virus or lack of magnesium(if the latter do I use Epsom salts?).
First time growing them in a greenhouse, and they were doing really well!

    Curly leaves are often caused by draughts - is the plant just by the door?

    Are they a bush variety? - I see the side shoots have not been removed

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    It happens a lot with older lower leaves, particularly on outdoor plants. I take them off to just below the first truss.

    One cause is rain splashing soil up onto the leaves.

    Removing them up to the first truss helps a great deal with airflow around the base of the plant and helps prevent blight too.

    The abundance of foliage to some probably would suggest healthy plants.  In this case  I'd suggest removing some of the leaves.  This will allow greater air circulation and to a degree help to avoid partly hidden leaves from deteriorating and possibly inviting bacterial infects etc.  I would have thought, that at this stage flowers and signs of fruits would be visible.  Perhaps a slight reduction with feeding.  Nevertheless, they appear to be very strong plants.  Best wishes for a good harvest.

    Thank you all for advice.  The side shoots i.e. Ones growing at 45 degrees at a leaf joint, have been removed when they first appeared. However I realised yesterday that two of the three had an additional 'stem' coming from the base-hadn't seen them due to all the foliage! So I've removed those, and lower leaves, and some which were shading the tomatoes (which look fine). They look much skinnier now! A lot of trusses on them so fingers crossed 🤞🍅🍅🍅
