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.
Typically, we advise people not to. If things don't go well, it won't be as clear which one is the problem. Also, in the summer heat, slow-release releases two or three times faster. People who do this successfully use a meter to tell them how many nutrients are in the soil. They might start with slow-release and end with water-soluble. But to do that well, you have to interpret the results of your TDS meter.
Hi! The fertilizer is 16% Nitrogen, 3% Phosphate, 16% Potash, 4% Calcium, 2% Magnesium, 1% Chlorine, and less than 1% each of Boron, Copper, Iron, Manganese, Molybdenum, and Zinc. Hope that helps!
We are assuming the palm is in a large pot. In that case, it can be more convenient to choose slow-release granular fertilzer in order to "set it and forget it." This also applies when you are working with any plants in homes or business spaces. In our greenhouse, we are dealing with smaller plants and smaller containers. We are also watering frequently and monitoring the plants frequently. We don't need our fertilizer to be on slow release, so it makes sense to use the water-soluble and be able to tweak what we are doing. Slow-release fertilizer leaches *into* the soil *slowly*, whereas water-soluble leaches *out of* the soil *quickly*.

Thanks for sharing that extra info!
Can I use both for my potted rose plant with 1 to 2 weeks interval.

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

125ppm is the recommended fertilizer per watering. Most plants do not need to be watered daily.
What are the materials that used in this soluble fertiliser?

Great vid exact answer I was looking for 🤩
hmm excuse me~ why many said granular is better for oil palm? Can you give me the answer? Thank you
