Thrips alright. Can tell right away from the patterns of the leaf damage. Can look like windows in the leaves.

In veg I use Safer's End All concentrate with 10ml/L canola oil for thrips or mites, sometimes both at the same time, but it leaves a nasty taste in your buds. You need to do 3 - 5 sprays a few days apart and be consistent and very thorough with your spraying. I toss a plastic sheet on the floor and lay the plants on their sides. Start at the bottom and work up rolling the plant to soak it down good. If I have more than a few plants I'll use the pump up sprayer and mix 2L in it. Tilt the bottle back and forth as you go to keep the oil mixed in.

In flower I've hit them with ISO and also gone in every day a couple times and sat there on a bucket hunting them down by hand. The adults are easy to spot but don't sneak up or they scoot. Just a light pinch with a rub kills them easy enough. As long as you can keep the numbers down it's not going to hurt your crop much if at all. On a couple of small grows when the plants were still small I've got rid of them all by hand. A 3" 3 - 5X magnifying glass helps a lot too. You'll spot a lot of smaller ones you might have missed. A loupe is no good for this stuff.

Good luck!

What is ISO?

Do you dilute the ISO?
Yeah. Think I used 30% last time. 99% diluted with RO water. Test spray on some lower leaves before doing the whole plant. Do some hunting by hand too as it doesn't look like there is all that many of them so far. So much easier to deal with than the Borg. (mites)

Thrips, nor mites, have any part of their life cycle in the soil so soil drenches are useless against them. For thrips, yellow sticky traps stuck in the pots or on the walls around the plants can help reduce the adult population like you would for fungus gnats who do lay their eggs in the soil where their larvae chew on the root hairs. Adult fungus gnats don't harm the plants tho.

Sometimes they try to lay eggs up in the flowers too, but get stuck and die. Eventually causing it to mold up. I hate when they do that..
They actually lay their eggs embedded in the leaf material and not on top like mites. Very hard to find thrip eggs anywhere and the black dots are their shit. They will crawl on the buds and get stuck in the resin tho. Mites walk across the resin glands like they aren't even there.

Couple of two-spotted mites and an egg from an infestation I had a few years ago.

Im gonna make a post, and it's going to Garner a lot of hate probably. I use liquid sevin on the outside of my grow area, keeps pests away as I live in a state that doesn't get cold enough to have large die offs. I've even used it at 1/8 concentration on my plants. It has a half life of anywhere from 2.5 - 10 days. But I don't sell anything and only grow to supply myself. Take that for what it's worth.

So, let me tell you my situation. I've thrips and it's nothing new, but it's def gotten worse over the past few runs. I don't bring anything in from outside and I only rotate my own moms and cuts.

I was using Spinosad, but I don't see the problem go away. It did minimize it, but it's not helping. At this point, it seems like they're immune to spinosad.

Right now I'm at the end of week 2 of flower. I'm seeing these bastards getting all around my nodes and I want to know if I can have a game plan before I really get a bunch of buds.

I'm open to ideas and methods, but I've never use Pylon TR and apparently it works. I've used Pyretherin TR, but that never worked. Right now, my veg is FILLED with thrips, and my grow is not that far behind. I can't find anything to get rid of it. I stick yellow stickies, but it's not working.

My goal is to completely remove them from my Veg, but I'm not sure how to do that. If I stop the problem there, I won't have a problem in grow.

Well, what is this stuff and what's it intended for? I'd like to learn more about it just in case it's something I want to keep in my arsenal. I spray Cyzmic CS around my grow area and home, but if this stuff can even replace that I don't mind!

It's literally a common garden pesticide. It's intended for killing bugs in gardens. I haven't encountered a bug it DOESNT kill. Yes I have smoked buds that for sure definitely have some on it I don't notice it at all and while I did make the flipper joke I have no idea what it does when smoked (7 days before harvest is as late as I have sprayed it). I've been using it for about 5 years when I first went outdoors. The area I live never has a pest off season and I was losing a lot of plants not just cannabis, so I've used it on tomatoes, bokchoy, squash even papaya.

I spray the sevin every 3 weeks at 1/8 the concentration recommended starting at 4 weeks old. If I wait until I see critters here it's usually already a full blown infestation.
