These particular plants are a dwarf form of English laurel. 'Otto Luyken' is very common. Chlorosis is common with these plants, often from poor drainage causing root rot, or sometimes iron deficiency from improper soil pH. They like a slightly acid pH, which is the general pH of soil around here, but who knows what it is in a raised bed like you've got them in. The soil is probably hauled in for one thing, and masonry can change the soil pH. Soil can vary tremendously from one spot to another just a foot away. These are not the exact same bush, you have a number of individuals of the same kind; and they are not all in the same soil, each one is in its own spot, which can have very different soil conditions. They look like they've been in for a long time, not recently planted. So they could be rootbound, but it could also be something like winter damage, or root rot from January's flooding, or a particularly good year for root weevils chewing on the roots could cause the yellowing too. See how wet the soil is where the roots are, and what the pH is. The soil should be starting to dry out by now. You do not want it to be wet all the time. If the soil is moist but not wet, and doesn't smell of rotting eggs, then try giving them some liquid fertilizer with chelated micronutrients. A shot of Miracid would be just the thing. See if that greens them up. If so then you know it's a nutrient deficiency. You shouldn't need to feed them very often though, maybe once a year. That planter you have them in does look rather crowded. There's as much root below ground as branches above. And you're watering them already?? seems early to me, you could be keeping them too wet. I haven't watered anything in my garden yet, just the smaller pots. Zone 5 is not incorrect for Tacoma, just it's zone 5 in Sunset Magazine's system. Zone 8 for Tacoma is the USDA system. Either one is correct, just you should specify which one you're using! 'cause zone 5 WA in USDA is Spokane.

It's a Lythrum of some sort. It could possibly be Lythrum virgatum 'Morden Pink' or a similar variety. If you look closely, you can see that the individual flowers have the wrong shape to be a Salvia of any kind.

Ficus galling wasp in Josephiella family. Been in Los Angeles areas for many years and the only remedy is to keep trimmed to lower foliage mass and remove cut foliage and dropped leafs from ground to lower re-infestation rates. However once you have them, you have them. I've had them on my hedge for years, its only unsightly, not life threatening. on the hedges we usually do a vigorous shear right around the time we see the galls appear and this will tend to remove a really good portion of the larvae and subsequent generations from the specific group of plants. https://palmbeachcountyextension.wordpress.com/2012/01/18/josephiella-wasp-galls-on-ficus/

The underside has a dusty look that can suggest mites. I am half blind and can't make out anything beyond that. Look at the underside with a magnifier. I need 5x or 6x If there is a mite problem, you will see lots of fine webbing and a few of the little crab-shaped critters, amber colored.. There will also be fine pale stippling on the upper face of the leaf. The remedy is a forceful spray of water on the underside of the leaves every day for several days. If there are no or few mites, it is probably spray burn from the malathion.
