what organic admements need to be add to soil to flower in
Good soil results in healthy plants that can express themselves quite nicely without any additional additives.
That said I may use ash water for a shot of pottasium, if I have ashes. I'll do that anyway during the growth period.
I'm constantly feeding, adding to the soil, but only in micro doses. Like the wind blew it in. Pixie dust.
Read Dank Frank’s posts, best advice. You won’t look back!How complicated do you want to get?
You can find this info in stickies here on ic and places like KIS organics or buildasoil etc
Simplest stuff..Blood.. bone.. kelp.. dolomitic lime/oyster shell flower.. add less N than PK and make sure your pH is safely in range after you have cooked the soil but seriously im not repeating the whole list.. for simple check the organics for beginners and more complicated search for Dank frank's posts around here.
In my opinion, most people are massively overapplying P. Recent trial I saw showed that 4-1-1 was what they found to be optimal for cannabis. Hope that is useful. I tend to want to run K a bit higher than that but agree on the P. Water stress leads to a need for high K, which is common in most grows.
Meta analysis of studies done over a period of years in Israel showed 4-6-5 to be the optimum for cannabis, as an all in one. I think saying people are massively over applying something is a bit too far reaching without knowing the media they are growing in. People here saying regular soil should have everything you need, then we must grow completely different grades of cannabis.
