I wouldn't use neem oil when the plant is in flower.... Turn instead to some Spinosad or Dr. Zymes Eliminator both of which are organic and can be used up to day of harvest.... they will kill thrips, spider mites, aphids, whiteflies ... any of the sucking insects. You'll have to spray the entire plant, top and bottom of leaves, stems, branches... but this WILL work for you!
Good luck!
