Since the ones in the paviours seem to have been planted 2 years ago [unless I'm completely misunderstanding the post] I'm wondering how well prepped the sites were when they were put in. They'd either have to be very small plants to fit in those gaps, or lots of paviours would have needed removing first to get a decent hole ready for a bigger plant ,and then replaced properly. Paviours aren't usually mortared in either - they're laid on a good ,firm base [often compacted hardcore with another layer of sand etc on top] then they have a dry mix, or sand, brushed into the gaps after they're laid. As @philippasmith2 says - the ground will be compacted regardless of whether rain gets through or not, and that has a big effect. It really isn't ideal nowadays [ certainly in the last couple of years with the way climate and conditions are ] to get plants started off well, and to ensure they thrive, so they would probably have been struggling from the word go. Alternatively, if the site's on heavy clay, that's even more difficult for keeping plants of any kind happy without some decent prep to the site. The larger, older hedge is completely different in it's site, because it will have been planted in a decent enough border to start with, and is established. Any difficulties it has regrading the weather will more easily be shrugged off.

Looking at the photographs from your queries of ‘21, ‘22 and ‘23 the problems seem similar … privet is privet, whatever the colour. The yellow is simply a ‘sport’ from a green privet which has been selected and cloned. Whatever the colour they need similar conditions and suffer from the same problems.

Different problen this was turning brown & dying off actually it has stopped now & is healthy.
I really don't get this at all now. You said the other, bigger hedge was fine at the start of the thread. The most likely explanation for foliage browning, or similar, is weather - frosts, wind and/or heat, and an established, otherwise healthy, hedge will recover easily after a trim. The other bits which aren't well established will suffer more, as we keep saying, especially if the site wasn't well enough prepped, and for the other reasons given re compaction etc. Aphids and/or any other sap suckers will also be shrugged off by the bigger, properly established hedge, while the other one will find it harder.
I'm afraid there's just too much conflicting information for me. I give up

OK lets clear this up all of this hedge is affected the only reason that the pictures sent to you were because these newer plants are hit the hardest. All areas have plenty of water because if we have no rain it is all irrigated. I tested the soil yesterday around the latest (2 year old plants) with adip stick & it was wet down to a foot of soil only soil no bricks or any other debri. etc. I have fed these latest plants within in the past 2 weeks. So let's say 100 ft of privey hedge all affected the same with whatever it is. 70% of this hedge has been there for 30 years or so. How can it be a problem with the latest 2 yr settings if all of it is affected.
There is a difference between a plant which has been in situ for 30 years and one which has been in situ for 2 years particularly given the extreme weather conditions we've experienced in the last couple if years. That aside tho, if you are convinced that the problem is neither weather nor ground/soil related you are left with waiting and seeing if the plants survive and thrive over the coming years.
I lost a privet hedge, was very over shaded by a huge sycamore. I've seen others suffer in the shade. And conversely common privet thriving on thin chalk soil in full sun.

But it all has the same problem so why?

Did you say you were 1mile from the coast? Or was that someone else? How about: salty winds.
