I've never had white fly's but I've had spider mites and thrips and I used to bomb with pyrithuium but not if the plants had less than 2 weeks left to finish. It worked for me but it doesn't kill eggs. Their life cycle is regulated by temperature. Decrease the temperature to as low as you can without harming the plants and it will take longer for the eggs to hatch. The only problem is when you lower the temperature and they hatch, they live for a longer life span than if it were hotter. When you have white fly's you have to watch out for mold. I would use the pyrethuium.

Exactly! I allow 3 weeks after a pyr bomb before harvest. I always bomb twice. Bomb, the drop temps a bit, wait 4 days, bomb again. This allows eggs to hatch and instars that are protected by location under the soil surface or within plant tissue (all depends on species where they are hiding, the little rascals) to emerge and become vulnerable.

The pyrethrum I'm using is in a vegetable oil solution so I would never use it on flowering plants with resin.
Not because of the pyrethrum - is quickly decomposed by the light- but I don't want any damn vegetable oil in my buds
If your pyrethrum also contains other stuff like piperonul butoxide then stay away from it once flowering has begun.
Live with your plague - treat your veggies - hope to get it right the next time Anyway your plants look healthy - you'll pull through without chemicals for the rest of the flowering period no probs.
