Maybe straight Vingar can Kill,I doubt it.
I've used it at times in a Hydro setup when I was out of PH up and Down.
It is also only a couple oz. of it per Gal.-after it reacted with the lime...
Read the Blossom set type products lables.
Most regular Vinegar is only 5% Acetic acid.
I found any other type vinegar had too much other stuff in it.
It made a muddy spray.
I use wich's brew as a soil drench to promote budding and bud set.
I don't like foliar (SP?) feeding my plants.
I don't want the stuff on my pods that a lot of people use that is popular these days.
Teas etc.,I'm VERY suprised people havent gotten sick from the stuff people spray their plants with.
I've gotten the shlits from some peoples pods that were sprayed with the popular stuff people brew these day and spray on their plants.
I see residue on pods-I toss them out,won't eat them.
I'm talking EXPLOSIVE Diarrea!
Dribbling down court etc.BIG TIME!
I'm very surprised nobdy has gotten Salmonella or ?from several of the teas/fermented stuff people use.
We was cooking utensils or use clean stuff when we cook,some even buy veggie washes for their food...
BUT the same people,use a dead fish,worm casings Etc. to make a plant spray.
Think nothing of it...
Might be VERY cool in the soil...microbes or?
On my plants and pods -no way!
