The garden is looking stellar @LionsNaughtyBeans. Show de bola
This sounds about right. I would also recommend trying to incorporate something like @Pigeonman’s FYPM recipe in your IPM regimen as well. It should be pretty helpful with Botrytis and other fungal pathogens. I personally inoculate my plants using different Trichoderma, Bacillus and other beneficial organisms from germination; but these tools are accessible & readily available here in the U.S. I imagine the same is true in Brazil and Canada; but haven’t looked into it.
I never prune/ top autos. I’ve recently learned that up potting (transplanting) has it’s applications but other than that or LST (coaxing /tucking leaves under each other or using ties/ wire) to allow for maximum light penetration to the different nodes at most, autoflowers should pretty much be allowed to “auto-flower”.
