    Hello mate, it looks like a zinc def to me.

    The clue is in the way the leaf veins have paled while the spaces stay green. If this was reversed, (leaf spaces pale and veins stay green) it would indicate a mag def.

    Try giving a few feeds at 5.6 ph and lower your ec a little as well, to 1.1-1.2 and this will help her recover.

    Damage done will not get better, look to what comes after this to judge her response.

    Good luck mate.
