Answer: Your tomatoes need a proper "balance" of nutrients. Packaged fertilizer should include on its label the Nitrogen, Phosphorous and Potassium ratio of 5-10-10 or 10-10-10. Both potash and calcium are important but they are included in packaged fertilizers as trace elements, especially if you purchase one formulated especially for tomatoes. Be careful not to over apply or you will have lots of stems and leaves but not many flowers or fruits. Enjoy your tomatoes!
