One of the benefits of fertilizing through drip irrigation (fertigation) is being able to have higher control over the fertilization program. If you notice plants are growing too much, reduce the rate or do not fertilize that week. It is easy to tell if the rate is too high by looking at the leaf number, size and color. Many big, dark green leaves and little to no flowering means the nitrogen rate is too high. In watermelon, there will be an excessive amount of up rights (ends of the vine) pointing up.
