Determining N, P, K deficiencies in strawberries through visual observations Identifying nutrient deficiencies in strawberries can be a tricky business. First off, disease symptoms are often similar to those of nutrient deficiencies and it can be hard to tell the two apart. Secondly, multiple deficiencies can occur on the same plant, which makes it difficult to determine which nutrient is the culprit.
