my recommendation is fix the next round in veg. Everyone should develop an IPM (integrated pest management) system. This doesn't mean nuking plants but treating them.
For every person that says brand X works and that Mix Y, there's a person who says the exact opposite.
The problem with a some pesticides and homemade mixes are that they are CONTACT pesticides. You have to spray everywhere, and pretty much drench the plant. Especially since mites like the undersides of leaves. The pesticides that seem to be more effective are TRANSLAMINAR and SYSTEMIC, where this is less important. Translaminar and systemic pesticides are usually pretty harsh though.
Basically the plants should be treated on a regular basis on a rotating pesticide/treatment schedule in VEG. Mite population thrives in most grow environments and can grow exponentially if unnoticed and untreated.
Mite populations can explode in higher temps, so you can slow growth down by lowering temp a few degrees. I've seen people use vacuums to clean the webs off bud.
I know of someone who has had mites for years, he said he thinks he will never get rid of them. Ofcourse I don't think he has really tried either.
If you noticed a while ago and are trying to do something now, well shame on you. If you just noticed now, the damage will be pretty minimal.
If you have ever bought weed, you've probably smoked mites.
