Hi there.
You are outdoor right? I battled them a couple of years ago and in veg, i was using a mix of h2o2, h2o and dishwash soap. Spraying all over but damn they are stubborn so i had to practically keep doing it the whole grow, once a week.
In flower its gets harder. So i was using a milder mixture of h2o2 and h2o only and spraying on affected leaves. Then comes the hard part, i was also individually taking them out of buds, leaves by hand and then wiping with that solution where i could.
Girls managed to finish and smoke was ok. Then i set out to find the source before next grow as it is likely that there is a plant nearby your grow area that has them a lot. For me it was my neighbour's tree with two big branches hanging in my yard full of them...i went there and asked for permission to bring the whole tree down. I was fine for a couple of years after that and now i have moved to indoor growing only, honestly where i live, its a daily battle with pests so thats why.
