Thank you for the replied.
So can I only use Chili JLF to plant the whole cycle?  

1. Chili JLF is best used for chili, but it can be applied to other crops as well.
2. There is no EC problem because it is diluted 20 times or more in water.
* JLF has no expiration date. The older it gets, the better.  

In the past 6 month I already planted around 1000 chili crop, but the output is very low. So I wonder is it not enough nutrient for the plant. I use only chili JLF and also fish amino acid.  

Crop residues JLF are the best main additional fertilizers because it has the exact nutrients that the crop needs. You're good, you've exceeded the manufacturing period. According to the book, 20-300 for dilution rate.  

How many times should I dilute from JLF?
