My lifestyle supports exercising in the evenings. What about my sunlight and air elements?

That's completely okay. Remember, incorporating the elements of sunlight and air along with your movement are add-ons, not necessities. 

You can find a way to spend time outdoors outside of your exercise routine, in order to nourish your body with nature's elements. You could do this by spending some time every week sunbathing, or even eating any of your meals in the sun!
