che - it's been pretty hot at times and sun has been blasting. I see a drip line - have you checked the soil under the mulch around the plants, a couple of inches down to see if it's moist? Are they planted in full sun? I would make sure they're well-watered before moving them. To me, it looks more like heat or dry stress. I wouldn't fertilize your shrubs or cut them back this fall. You don't want to promote new growth going into winter. Early spring should be fine for trimming them back while still allowing enough time for flowers. Once you move them this fall, make sure they get an inch of water per week (irrigate if it doesn't rain) until the ground freezes.
