The plants with high levels of cuticular wax don't absorb foliar feeds well. Remember too, foliar feeding is a very inefficient way of getting nutrients to plants, and effectiveness also varies with what nutrients are being applied and in what form. If foliar feeding is required, or makes a notable difference, you (the collective 'you') probably should be looking closely at what might be wrong with your regular nutritional supplementation program because roots are by far the most efficient pathway for nutrients.
