Spent Seeds but my profits decreased?

Seeds act as a significant, static profit percentage bonus for all of your crops.

The amount of profit bonus you get from them depends on how many Seeds you have in reserve at the moment. If you spend a large portion of your Seed reserve at the Shop, you will end up decreasing your profits drastically.

It’s always a bit of a balancing game to figure out which upgrades are worth buying and when: for example if you have 27 million Seeds and spend 25 million on an upgrade affecting just one crop, you will likely see your overall profits take a hit.
