I wasn't keeping track of week #s, but after the flowers began developing I stopped spraying my plants with Neem/Insecticide soap and placed sticky strips around the base of the plants.
These strips were 100% worth it and I believe they saved my harvest quality or possible the entire grow, there are hundreds of thrips/fungus gnats/aphids/earwigs stuck to them. Unfortunately some spiders as well.
Im still out every day looking for bugs, but the strips really put an end to the bugs coming back
