This is the one I use in that vein. Not for the weak of heart. It's a nightmare to work with around, as it will peel your face down to the bone, blind
or kill you.



Plus it needs a carrier, because SA is not water soluble. This acid is prone to particulate in air, so I don't use it often. Sometimes will mix up a batch in early flower, if I have a few drifting though. It sits on the
biohazard shelf w/lid tight.
Covering arms/eyes/cloth face covering is mandatory.
Put into 2 tbsp veg glycerin, then solubilized in aqueous. ---->1000 ml h20 then pH balance.
As for ppm, I don't have much idea's, I've been using "a little" because it's exceptionally acidic in vitro, the plants have limitations.
Small enough it not kill da plants. Certainly not 5000 ppm, more like 5000 ppb (billion) = (0.5)ppm Maybe 1/32->1/64 tsp (tiny, tiny pinch) per liter, (do not use your fingers)

and requires rebalancing. And that often has to be diluted further.
No question it increases the bud setting process, but so do a few different ways, it seems. (ie. humic/fluvics) Bottom line,
It works, but it's certainly not my favorite chemical to work with. My skin burns just looking at that bottle, lol.
face peel anyone?
Salicylic acid is in many wash-off and leave-on products in concentrations between 0.5% to 2%. Salicylic acid breaks the bonds that hold the cells together
