Yes, way too much fertilizer. Plants need fertilizer in proportion to the plant size and growth rate. Generally, tomatoes are fertilized with a high phosphoruse (middle number) +moderate nitrogen fertilizer when they go in the ground and then nothing else until they set fruit , at which time they might be given a high nitrogen fertilizer to offset the needs of rapid growth.
Crystal fertilizers (blue die) are designed for use with container grown plants growing in potting medium that does not have any nutrients. The ratio of root space to plant volume is low (small pots) and the pots are completely flushed out so there is no fertilizer build up. This is one reason box instructions may have higher concetrations and application rates than are good for plants grown in the ground. Soil has its own nutrients, and holds onto any fertilizer you add to it, and roots have the ability to go searching a wide area for more nutrients.
