    Thanks.
    Will it affect the plant? and should I treat the plant in anyway i.e remove the affected leaves?

    Leave them on & pray for warmer weather. It'll slow the plant down but it should recover. I've got one thats been outside for a couple of months now, it had similar damage on its earlier leaves, but has recently put on a growth spurt, despite the cold weather.

    The tomatoes are swelling up now too & its getting more flowers.

      It's lack of phosphorus that causes that purple discolouring in the leaves. The plant can't absorb it in cold conditions. They will recover when the weather warms up.
