Things to Consider:

The three main things to keep in mind when selecting a water soluble fertilizer are the NPK ratio, the type of fertilizer (e.g., fish emulsion, seaweed extract), and thechelate.

The first step is to identify what type of fertilizer the plants will need based on their current NPK levels. For example, a plant that is deficient in nitrogen will need a fertilizer with a higher nitrogen content. The second step is to select a fertilizer that contains the right type of nutrients for the plants. For example, a plant that is deficient in phosphorus will need a fertilizer that contains phosphates. The third and final step is to select a fertilizer that contains the right type of chelate for the plants. For example, a plant that is deficient in iron will need a fertilizer that contains an iron chelate.

How We Pick & Test:

When it comes to finding the best water soluble fertilizer, there are a few things that you need to take into account. The first is what type of plants you are trying to grow. Different plants have different nutrient requirements, so you will need to find a fertilizer that is tailored to the specific needs of your plants. Another important factor to consider is the soil type. Different soil types have different pH levels, which can affect how well the fertilizer is absorbed. Finally, you need to consider the watering schedule for your plants. Over-watering can dilute the fertilizer, making it less effective.
