    Are you using the same compost?
    Dordogne and Norfolk. Clay in Dordogne, sandy in Norfolk.

    Not the normal stuff I use, to be honest it’s rubbish, more wood chip in it to bulk it up, it could be lack of nutrients

    Wind burn in a conservatory?

    No doors open, only windows for a flow of air way above the plants

    I am no expert . Could it be damage from a rather cold night especially if the windows are left open at night .

    I know it's in a conservatory,  but is it unheated? I would guess the plants were near the glass ( say the size /depth of a windowsill) and the radiated cold of the glass reached the leaves. If this is so then they will recover without harm @Tall trees

    yellowing leaves can mean the plants are hungry. They aren't flowering yet, so it probably isn't that, but then again you say the compost is a bit poor, so maybe they need a bit of a boost.

    bean plants make their own food.

    To say legumes make their own food is stretching things somewhat. I wonder how much nitrogen fixation can take place while plants are growing in MPC and constrained in pots.
