yo in outdoor I use preventatives and I’ve tried various things and what works best for me at the moment is neem + potassium soap every 15 days. Then I spray either Solabiol + Spider Killer (pure cinnamon extract) or Spidermite SMC, you can combine Solabiol and the spray, it’s one type and the others are just spider. I do this every 7 days and the spray can only be applied up to 3 weeks before harvest, but I wouldn’t push it that far. I use diclofenac for powdery mildew a couple of times or three throughout the grow, and I only apply that with the other stuff. The thrips and that go away quickly with just the spray, but I’m telling you, I have zero problems this way. Last year I used Brotipot and it worked well, since this year I haven’t used it and I’ve had a few with botrytis, but well, that’s what I do and I would try with spray + SMC for example or spray + Spider Killer or the same but Solabiol instead of spray.😎
