Wash off the soap you sprayed it with. If it's a detergent, the surfactants can burn the foliage in hot sun and high heat. If it's an insecticidal soap, that's "lard" (potassium salts of fatty acids), or FAT and fat is an oil, which will also burn in high heat and direct, hot sun. Personally, I would remove damaged and dying foliage; keep it appropriately watered and in filtered light, not direct hot sun (if it's already hot "summer" conditions there, if not and the light is bright but not blistering, then sun should work) until new growth begins. There are stored nutrients in the canes which the plant will use to produce new growth. Why deprive it of those stored reserves? Once you see new growth emerging, you can start feeding it as you feed the others. I'm sorry, but I know nothing of the variety, but how you treat it to acclimate it to your conditions is the same no matter which "class" it is.
