Search and see if it is "systemic" ... if it absorbs into the plantand remains there, that's a problem, like Eagle20, or whatever it was called. If it doesn't enter the plant, the new growth won't be contaminated with it if you never sprayed that new growth.
i can't read what the active ingredient is on that bottle. google that with "systemic" or "half-life" or "how long to break down" etc... 'biodegrade' swapped for "break down" .. eventually you'll see a reputable source talk about these aspects and whether you have to worry.
"Organic" does not mean safe to spray on the plant. Don't believe that very dangerous and false idea. Plenty of organic molecules are absolutely toxic to the human body. Plus, the way it's used here is just a marketing term. it has no real causality relative to how a particular molecule may or may not act / react.
I wouldn't spray anything on flower, but outdoors is a different animal....
