I had the same problem with the little flies when I put my three plants to flower. Got some Orange TKO organic stuff we have for cleaning and shooing away the ants. Works well. Just dilute 1/2 teaspoon per 24 oz. spray bottle. You can mist the leaves and the soil around the plant without hurting it, and might even be beneficial, seeing as its organic and comes from orange peels. I spray the soil each time I feed or water. Haven't seen any flies since I began doing this. Good luck. :smokin:
