That's thrips all right.
That spinosad will take you from horribly infested to completely wiped out overnight.
I would come back and hit everything again with it a week later.
Spray everything, undersides of leaves, mainstem, dirt, all rooms/boxs
I've sprayed everything from seedlings to plants that were days from harvest with no harm to the plants, but plenty of harm to those bastard thrips.
I may be wrong, but that doesn't look like any thrip damage that I've had before...are the black dots what the damage is supposed to be? Thrips usually leave shiny/silver like streakes on the leaves when they have attacked my girls...I never saw any type of black dots like that...Good luck taking care of it, and I hope it never comes back!
as all ready said above predators orius laevigatoys is the
only solution when the plants are mature.
i bogout those predators one time and since then i dont see any thrip around.
i hope this spinosad kill them, but you have to repeat once more
after few days.
Get anything with Spinosad in it.
