That's what I am looking for. But Peters is unvailable in EU, and Yara not available in my country. Found 25 kg for 60€ but I am not sure about amino nitrogen.
Water-soluble fertilisers are nutrient-rich compounds that readily dissolve in water, making them easily accessible for plants' root uptake, promoting growth.
The cannabis growers that I know that use Yara are using Yara Brown and Yara Calcinit.
They start with A (Calcinit) and B (Yara Kristal Brown - some use the Orange) in the proportion 1:1 in the first week.
And they build this up to A:B in the proportion 1:1.5.
(be careful how to mix!)
I also know growers who use Peters Combi Sol.
Most add a bit of Epsom salt then (same with Yara Orange)
Peters is available in Europe as @Florere already stated. It is JR Peters I think that is not available.
I don't think so, but again: I am no expert.
Perhaps it is a little low on P (when you use Brown with Calcinit)
But most people add extra P anyway when they use pH-
So the P numbers could also be ok probably.
The Yara Brown is used by growers with a good reputation and they have solid and great yields.
