Thrips?

These white spots on these leaves have been bugging me for a while. I know deep down they’re thrips and I’m setting up the air compressor and HLVP sprayer in a few minutes and giving everything a good blast of spinosad. I don’t know much about these little fuckers, and this is my first run-in with any plant pest other than caterpillars. I bought the spinosad because it’s safe for my four legged children (even used as flea medicine for dogs) and it seems like the best non-toxic pesticide, and it says right on the label that it kills thrips (and caterpillars). I haven’t had any caterpillars on my outdoor plants yet but I’m glad I bought this stuff ahead of time.

Before I proceed, could this be anything else, or is it time to blast the tent? Do I need to do multiple treatments or any follow-up measures? I think they came in with that shitty soil I had to buy from Lowe’s because of the perlite and vermiculite shortage.

Spinosad worked great for my minor thrip issues. Alternating spinosad and BT was my regime when I did outdoor.

Indoor. I was a big dummy, unknowingly bringing the trips into the grow. On my clothes....shoes....hair.

I see one thrip, but this white thing on the leaf looks like crystalized salts. Do you foliar feed? Did you try to gently scratch it down?

Next time buy you some yellow or white sweet clover seeds and if you are growing outside and your plants are in pots sprinkle a little in your pots to make it a companion plant, and the pirate bugs will come and stay and keep your garden free of all pests, and if you have your plants outside in the ground just sprinkle a little on the ground to make a small patch near your plants and if you are growing inside, a single 1 gallon pot with sweet clover will cover a 20 x 20 area. and to make those pots, plant some sweet clover in 1 gallon pots, then when you need some pirate bugs, place the pot with the sweet clover in it outside for a few days in the shade, then after that, after dusk move the pot to your grow area, and your indoor garden will be 100% protected from any pest that could harm a cannabis plant, or if you already have a infestation, it will be no more in 3 to 5 days! Yeah, simple nature derived preventive pest control will save you and your garden from all kinds of unnecessary troubles!

I never foliar feed. The only time the leaves in the tent get wet is if there’s extra humidity and some condenses on the top of the tent. They were on a lot of leaves and the one in the pic wasn’t even the worst. I cut off all the really bad leaves and fed them to my landlord’s goats (my weed leaf disposers lol) and blasted the tent with about a pint of spinosad solution in a HVLP sprayer with the compressor at 70psi.

I’ll try that outside next year for sure. I like to grow in the ground because I have killer soil where I live. Lots of agriculture in my neighborhood. I am a big fan of biocontrol and love info like this. Thanks!

I’ve never seen them outside and my best guess is they came from that cheap potting soil I had to buy (finally broke down and ordered some expensive perlite and vermiculite from amazon). I used to grow mushrooms and am well aware of the risks of bringing contaminants in on your clothes. I would take a shower and put on clean clothes and wear a surgical mask for any work I did with mushroom cultures. I’ll get some Bt too because I believe in alternating treatments. Hopefully the spinosad spray and physical removal of the worst leaves will take care of them.

So I’m not sure what the white spots are. I’ve looked at them closely and can’t figure it out. I cut off and examined one of the worst leaves, and when I turned it over noticed these little green bugs on the underside of the leaf. Anyone know what they are and what to do? I didn’t have any of these problems until I bought that bag of soil from Lowe’s.

Thrips. Why it took you so long to just look under the leafs I don't get. Thrips are so easy to spot.

Just my lack of experience showing. I haven’t been at this that long and still make plenty of mistakes. I thought they were actually the little white spots. Stupid I know. All my google searching just showed the white spots. I usually think I do pretty good research but I just got confused in the way that noobs do. As much research as I’ve done, “look under the leaves” is something I didn’t read anywhere. So basically I confused the symptom for the cause. I guess the first blast of spinosad didn’t get them all.

well thripse are easily diagnosed by their pattern of leaf-damage they leave...

many leaf-sucking pests hide under the leaves to escape the rainwater, always spray there first

Yeah this is all stuff I’m learning for the first time. I don’t have much experience with bugs because I’ve only been growing for a year and a half. Now I know, and if I hadn’t made this thread and exposed my lack of understanding, I’d still be misinformed. Looks like I just have to keep treating. I guess it goes without saying that I shouldn’t move anything in or out of the tent until they’re all gone. Sucks because I was going to give a couple clones to my friend but I don’t want to be introducing pests into her grow.

Bugs eat the underside of leafs for the most part and are usually found under the leafs. Majority of pests you can see with the naked eye and are easy to I.D., the ones you can barely see are mites.
