You won’t see some bugs. But basics first cause downturned lower leaves yellow with new growth good ain’t a bug. In veg as a preventative I spray
neem oil to rid bugs so you might want to start some program. Pest better dealt with before they’re in the plants.
Soil?
Ph?
Nutes
Feeds and when if any yet.
How often are pots dry? How dry do you let them get too.
I’m no dr of the plant but anyone is gonna want to know those basics. You do not have a serious issue yet from what I see.
I’d start a pest management either way and check your ph and all let people know the grow details.
