The best product to use would be SB Plant Invigorator since it's safe, non toxic and effective (effective against spidermites too but I digress). Since getting that might be a headache on a flowering plant at your stage, I would strongly recommend going down the route of using an insecticidal soap that suffocates the aphids. You should specifically get one with an organic clearance and there should be no problems. It'll probably say on the label that it's safe to spray food crops and pick/eat on the same day. That said if you can, try and avoid spraying the buds directly if you can at all help it.
As laugh suggested, for a belt and braces approach you could also use pyrethrum, but specifically one an ant powder (works great against thrips, too) which you simply sprinkle onto the soil surface. For a couple of days preferably water from underneath although this is not essential. It's safe and works! The insecticidal soap should be effective on its own though if used correctly.
Insecticidal soap is what is known as a contact insecticide. For it to work, it must come into contact with the aphids but this is an advantage because unlike systemic products it isn't absorbed into the plant, persisting inside your buds until you harvest and smoke them. In fact it is actually extremely safe to use. One brand in particular I would recommend is Savona although I don't know if that's available online where you live or not.
