Hi Dave your cypreeses may have Iron Chlorosis but not all of them at once.

Try Iron chelate on a few to see how they react. They need iron as a normal
nutrient.

I'm a bit conserned for the health of my Leland Cypress. Wanting big fast
growing trees to screen us from the road, we have been planting a number
every
year. We now have about 20 trees with heights from 2' to 9'. The past
winter
was a bit harsh and they are all now sort of a yellow green rather than a
deep
color. There had been lots of snow and now lots of rain, so I doubt they
are
drying out. Any thoughts?
