Leaf damage/ weed killer- multiple plants


I am very new to this site and gardening so please forgive me if I don't use the correct terminology.

I have a few well established plants in my garden, which are very near my paving area.  We had a huge problem with weeds growing between the joints of the paving and needed to to re-do the joints with sand and seal the paving - the suggestion to do this was use weed killer on the weeds- which I did with a self squiring pump on all the paving.  3-4 weeks later the weeds have died back but a number of my plants now have leaf colouration issues and I am very worried that I might have damaged my plants or if in fact the issue is not the weed killer and there is something wrong in my garden.  The plants affected are my red acer, green acer, both of which are in a flower bed next to the path and Magic Seasons (Hydranga) type plant in a pot on the patio area.

Could anyone confirm if it is in fact the weed killer that has damaged them - if so will they die or if this is a different issue all together and just coincidence that it has appeared after I used weed killer on the path.

I thank you in advance for any help or advice you can give me

    Looks like overspray from your weed killing exploits. This is why you must always do it on a still day.

    Sprayers form a mist which we can see, a finer mist which we can nearly see and aerosols which we can't. You've managed to catch your plants with one or all of these. 

    They are big mature plants and hopefully should withstand this wee bit of damage. You'll soon know. If the look is bothering you remove the leaves but unfortunately any systemic damage is done already. It's a matter of wait and see now.

    Thank you so much for your very quick response - I thought it would be the weed killer.  Fingers crossed they can survive the trauma I have caused and lesson learn't - don't use weed killer near my lovely plants!

    Much appreciated imageimage

    We live and learn.

    When I was doing hands and knees weeding yesterday I was formulating a plan for jelly weedkiller I could paint on with a paint brush for spot treatment. I realise it has already been invented but where's the fun in buying it? image

    Help"! I noticed this this morning.

      It is leaf damage which appears to be scorch or could it be something worse? This is on a several Rhodedendron and Heuchera leaves and another Heuchrea about two fences panels away. no sunshine here for about three days.

    My only other  thought is the two little boys next door and their mother who were playing with super soaker when it was very hot and sunny.

    My Rhodie is the same, definitely thinking leaf scorch. They seem to be more prone to it. 

    For weeds, I just use boiling water from the kettle on the drive paving - much more environmentally friendly & just as effective.
