Sour diesel and an Enigma

One issue with predatory mites in late flower is they can get stuck in the sticky trichomes. There is no easy solution. One option would be to use a contact kill pesticide but wipe it on the big fan leaves where they hang out vs spray, it would knock the adults dead and doing that multiple times till harvest would keep them in check. The risk of it touching the buds is the main draw back. but some pesticides have a short half life and are gone by the time you need to harvest so any of they rated for use in flower could work. just don't spray. wipe/paint it on the leaves. Sticky traps are best static options with no issues of making the buds weird with chemicals or mites. Can also treat the soil line with some DE or spray on some pesticide. this way the young ones coming out of the soil will be targeted. BTi/BTk I think targets the thrips in the soil so that's a easy and safe method of killing them. Use a strong concentration of it. Nematodes are also an option. This is also a good lesson on having some form of IPM or integrated pest management system in place. Introduce the mites/BTi early in veg so they can chill out and wait for a tasty meal. I saw some thrip dmg on my outdoor plants and got a bunch of mites in little sachets, they cleared em all up but again not in bloom was in early veg.
