Welcome to GoY, Bbrian!
We don't mean to be nosy parkers, but we need more info:
What kinds of plants are these? What is the sun exposure? How much and how often are they getting watered? Are they in pots or in the ground? Have they been fed recently? Etc., etc....

Yo can add this info as a comment under this one.

Everything seems to be suffering from the dry weather, in spite of watering. Things in pots seem to need twice as much as you think! That's as long as you are not over-watering of course, which can also cause yellowing of the leaves!
