yes it is ok to use bombs when the plant is in flowering smoke. I of course dont like to touch anything in flower but , if the lil fuckers are eatin the crop , then go ahead , i have used bombs as far as a little over a week before pick ! remember Hot Shot in the blue can (its a deeper reach and dont have a residue) i accidently used the green can once and it did not hurt anything but the green one leaves a tiny bit of residue , which is good for the mites but not for the taste! I used hot shots twice last week on some horrid lookin plants and it didnt hurt them at all!!! (This has been the only time i was ever scared to use the shit because of how much stress i already put the thangs through , and it did nothing but kill bugs! ) Good Luck Smoke!
