Understanding Fertilizer: Water-Soluble V.S. Granular Slow-Release

As you plan your fertilizer program for your greenhouse or outdoor crops, you’ll want to know the difference between water-soluble and granular slow-release fertilizers.
There are advantages and disadvantages to each. And which you choose will depend on the needs of your soil and plants throughout the growing season. You may choose to keep both for use on different plants or at different times.

You kinda touched on it with water soluble, however slow release is slow release due to the need of microbes, and bacteria to break it down. This is fine for gardens, and what not, however for potted plants they generally don't have enough soil life of effectively break down slow release in a timely manner.

In situations like this water soluble is a better solution, it does not require soil life to break it down and convert it to a form for the plant to absorb. Which is why it's fast acting even potted plants can readily absorb it quickly.

For example, the recommended liquid fertilizer for plants is 125ppm. So that is the daily watering level?
