What's everybody flowering out with in their organic soil? Cow patty teas, Pot ash, Organic boosters etc etc..
Just about anything and everything Mother Earth offers.
Seriously though. I'm more seat of the pants, read the plants rather than an exact formula. But here's a general idea.
From about 7-10 days before flowering begins I'll change the base nutrient ratios to better suit bud set, either top dress or liquids. I'll feed her with a P:K ratio of 1:2 or 1:3. Fulvic and humic acids are included, as is some sort of seaweed extract, B vits and micros and bio inoculates. Currently using BioAg CytoPlus 1 week before flower as well as in week 1 and 2 of flower. The Cyto takes care of K, seaweed, humic acid and micros. I don't worry about reducing N until week 5 or 6, maybe 7 depending on how she bulking, how much N I think is still in the soil and how long the strain goes. I'll change the P:K ratio a little over the weeks to end up feeding the last week with 2:1 P:K or sometimes just P.
I rotate sources of nutrients. 3-4 weeks into flower I faze out seaweeds and molasses, and I never use fish after week 2, or Superthrive after wk 5-6.
I try to top dress dry at a rate that will leave little left at the end. Over the course of flowering I want the dry ferts to run out and finish on just the liquids.
Not including N sources, here's a list of some of what's on my shelf....
Earth Juice Big Bloomin Guano 0-4-0
EJ Bloom 0-3-1
EJ Meta-K 0-0-5
BioAG CytoPlus 0-0-7.5
DynaGro Pro-Tekt 0-0-3
Liquid Seaweed (by a former site sponsor)
BioAg Ful-Power
SuperThrive
With dry ferts I blend my own recipes to suit. Here's some dry components I have on hand....
Neem meal
Kelp meal
Blood meal
Shrimp meal
Crab meal
Espoma Gardentone
Langbeinite
Epsom salt
Oyster shell flour
Gypsum
Espoma rock phosphate
For slow release minerals I have Azomite, Cascade minerals and CBD minerals.
And I've been known to make weed flower head teas. Thistles mostly because there are plenty around.
That scratches the surface.
