hello,
I live in a country where growing and using cannabis is highly prohibited. I have a couple of plants outdoor which need fertilizers. We have Agro Markets which have a lot of different fertilers, but I dont know which one to choose because I cant tell the seller what I need it for.
The question: what plants are most like cannabis, so I can ask the seller for a fertilizer that will be good for my cannabis plants ?

thank you

Anything for tomatoes will work great.


However, I would personally look at NPK ratios. Look for like a 10-3-1 for veg and a 5-3-5 for flower. Basically the middle number can stay the same, but you want higher first number for veg and higher last number for flowering.

10-3-1 ? that little ? I bought NPK 16% and spread them on my plants ... my plants are only 30 cm tall ... did I harm them ?
 
Do you have a PPM meter? You can buy them really cheap.

I always go by PPM. For a vegging plant, I start with 400ppm of ferts, that doesn't include whatever the water was at. So if my water is 150ppm, then I add 400ppm of ferts, making my total 550. I see how they do with that first.
