Basically if your spinach looks healthy, then it is probably happy. But if you suspect a problem, a good place to start is to get your soil tested. The results will tell you if your soil has any deficiencies. You might check your county’s Cooperative Extension Service (see http://www.almanac.com/content/cooperative-extension-services ), which may offer information on this topic. In general, spinach likes quite a bit of nitrogen and moist, not soggy, soil. A soil pH of between 6.2 to 6.8 also helps. Nutrient deficiencies may appear as yellow or pale leaves, stunted or distorted growth, purpling or bronzing of leaves, leaves dropping early, or other symptoms. Hope this helps!
