Tried and true...did it many times.....DE foiliar spray slurry knocked the he'll out of aphids and white flies also......eliminates them quickly......my infestations started prior to flowering, ergo most of the "dirty leaves are gone before harvest.....I'd rather not spray buds with all that particulate (probably would wash up nice) . Be sure to cover soil when spaying so pests don't fall in substrate.
