Otto Luyken (Cherry Laurel) disease question

I have three cherry laurel plants in my front yard. This year, two of the three have a horrible problem where the tips of the leaves turn brown and die, causing the rest of the leaf to turn yellow, then brown and die. It has stunted the growth of the plants quite a bit. I don't see any pests, and have sprayed with a couple insecticide sprays, which helped earlier this spring but have since stopped helping. It doesn't look like shothole (which is common to these plants), and what's stranger still is my third plant is robust and healthy as can be. I have photos if anyone is wanting more details. Does anyone have any idea what could be causing this?

Yes, we need photos.

Beyond that, when did you plant them? I ask because brown tips sound like a q=water shortage.

But as said, please post images.

Updated: I added photos.

The plants have been there at least since I moved in to the house, three years ago.

Have they been getting enough water?

They are watered 3x weekly with my usual yard watering.

I have been doing a couple extra watering sessions with these shrubs due to all the questions about watering, and it stimulated a few new leaves to branch out, but they already have the brown tips, even immature in size..

I had six otto luykens in front when moved into house. Three died, yellow leaves turn brown,dropped. When I pulled dead shrubs out noticed base trunk bloated and oozing with wormish holes. Peach borers love cherry laurels. Purchased Bonide 8, Borer/Miner concentrate and have been able to save remaining three (though some pest damage present). Have planted three new also and spraying those also and keeping well watered.
