Nutritional monitoring in lettuce

Lettuce requires medium levels of fertilization, growing best with 150 to 200 ppm N or 1.0 to 2.0 mS/cm for hydroponic nutrient solutions. Lettuce transplants grown in soilless substrates have a wider optimal pH range of 5.5 to 6.5. Hydroponic solution pH values should be maintained between 5.5 and 6.0 with an optimal value of 5.8. Excessively high or low salts can significantly affect the quality of greenhouse-grown lettuce. Additionally, tipburn caused by calcium deficiency is a common issue.
