Keeping your sprays organic based is a good starter, just use edible friendly products and follow directions to stop x weeks before harvest, I'd recommend 2 weeks minimum if yours don't specify. I like getting my plants out for a good clean too, the only drawback is that you might bring nasties back into your grow space, but the benefits are worth it.
Your plants should be fine, but some plants are more heat sensitive than others.
