I have snooped around the internet tubes and I have learned that success can be made with traditional fertilizers in proper amounts.
Also, some nutrients can be ordered by Amazon, including CaL-MaG (essential for tomatoes and peppers), so there is that.
I have seen liquid fertilizers in shops here, but I cannot read Chinese too well, so I am not sure exactly what is what. I bought a bottle of this
and my boss read the instructions, but got hung up on the chemistry. She said it was for plants.
Any way, that is my update. Thanks!
