The Crape Myrtle looks like the watering was forgotten on it for a crucial time or two. Keep an eye on it: as hot as the Southwest has been lately, a Crape Myrtle in a pot will need watering every day.
On the Abutilon, I'm not seeing the diagnostic blotching of TMV. What I am seeing is serious starvation for various nutrients, especially nitrogen, magnesium, and manganese. That may also be compounded by chronic drought, and sodium poisoning. The aftermath of a severe case of aphids may also be involved--it sounds like a hard life, to me! I can't see if it is in a pot or not. If not, drag the hose over, and pour a good 50-60 gallons of water on it to leach out the sodium. Applying humates before the leaching will make it even more effective. Follow it up with a dose of a complete liquid, low phosphate fertilizer with micronutrients. Slower granular fertilizers can be applied a few weeks later, to keep up the recovery.

Awesome. Thanks so much! The abutilon is in a pot. Should I still leach or just start the nutrient treatment?

Leaching is still good, but you will probably only need 5-10 gallons to do the job, and no need for humates.
