Honestly that’s what I thought, I know I have thrips because of those silvery spit stains and I’ve seen them, but I have no idea what’s causing that leaf damage. Soil, PH, nutrients, and climate are all in check.. so I’m thinking could the thrips be a carrier of some sort of virus?

At its worst I could only find maybe 5-6 per plant crawling on the leaves, when I found them I did the h2o2 and water spray and covered the top of the pot with sticky traps. That’s when shit got crazy because 2 days later I removed the sticky trap and saw hundreds of tiny black thrips stuck to the trap. I’m thinking very few were able to surface though because the entire top of the pot was covered for each plant.How bad was the infestation? Like several live ones on every leaf at it's worst?
Gotcha. I've had some very bad thrip damage before that I thought was something else. Didn't look exactly the same as yours but ugly enough in its own way. My infestation was maybe a bit bigger. The spinosad will knock em out with repeat applications though.. Be patient. Personally I think your okay spraying spinosad a few more weeks if needed. Others may disagree, that's cool..At its worst I could only find maybe 5-6 per plant crawling on the leaves, when I found them I did the h2o2 and water spray and covered the top of the pot with sticky traps.

it’s hard to find information on how late into flower you can spray spinosad, some people say up until a few days before harvest well others say they’d never spray past the first 2-3 weeks, and I’ve even seen people say they only spray in veg. Anyway I’m really just wondering if it looks like thrip damage, it’s hard to find any pictures resembling this type of damage. I guess only time will tell but as of now I can’t find any other pests that could be causing a separate issue.Gotcha. I've had some very bad thrip damage before that I thought was something else.

That’s not thrip damage, it looks like you burned them with a spray to me. Also I never seen thrips jump around, let alone in soil. Sounds like spring tails in your soil, and probably fungus gnats. Thrips like the bottom side of your leaves. Identify your bugs and go from there.Does anyone else have any information on if they think this leaf damage is related to the thrips or a separate issue?
thrips are born inside of leaves, crawl out of them, feed on them, crawl into the soil where they pupate, then come out of the soil as an adult. You can find thrips on any part of your plant and in the soil, they’re some annoying ass bugs. And I didn’t burn my leaves, they starting showing that appearance and slowly spread like a virus growing more and more, and now at this point I can’t find a single bug no matter how hard I try but the leaf damage continues to progress.That’s not thrip damage, it looks like you burned them with a spray to me.

Thank you for the advice I’ll give that a try.I think that is calcium depletion and would recommend a giant handful of gypsum
Thanks for the observation, it’s very possibly I have been overwatering recently with soil drenches trying to kill the bugs. As for the leaf septoria I looked into it and I think that might be the issue, I read it can transmitted by pests as well. Luckily it said it doesn’t affect the flowers only the foliage, still looks like a diminished yield this season unfortunately, luckily I grow small scale for personal use only.ok firstly i don’t have a lot of pest experience also but to me those spots or some of them look like leaf septoria..
also some if the damage on the leaf edges can be from overwatering as with leaf septoria.
Hard to imagine it’s a problem of excess nutrients, I only use dry amendments so it’s slow release, then I’ll top dress if necessary. Starting to think I have been overwatering though trying to kill these bugs.Burned leave tips (which most of yours have) are almost always excess nutrient. The really burned leaves are either further nutrient burn or a watering problem.
