Well she had so much damage few weeks ago cause of some oil that felt on her... ive made a trap (old style) for the white fly (yellow paper with oil) and the oil felt on the leaves destroying them... now is recover and the flowers are getting bigger...
Unsure, offhand, what remedy you should use as I've not had this problem that I can recall. A spray I've used for foliar cleaning between foilar feeds (as seedlings only) contained Palmolive dish soap, some crushed garlic steeped in mineral oil overnight and strained (then discarded, keeping only the oil mixture) and some water. I believe I used this for thrips (white flies) though and a general cleaning. And I stopped before the flowering light schedule switch.
@Will_journals, is diatomaceous earth!!!! i think is the best organic insecticide, the fine powder adsorbs lipids from the waxy outer layer of the exoskeletons of many species of insects; this layer acts as a barrier that resists the loss of water vapour from the insect's body. Damaging the layer increases the evaporation of water from their bodies, so that they dehydrate, commonly fatally.
