Adult thrips can look like small black flies. But they aren't attracted very much to the yellow like other flying insects. Their favored color is blue. Blue stickies can help identify a thrip presence as they can be very hard too spot. But by no means are sticky traps a good eradication method.

@Ttrichome How should I treat them best, with hydrogen peroxide?

I'm on the road right now, but I can take a picture later and send it to you, if it's really thripse I should buy and use nematodes, have heard they should be very good against thripse

In the second pic bottom right leaf I see what appears to be 2 small bugs. If your symptom is stains and Marks I'd guess thrip nymphs. But without a clear view hard to say. Take a good look on ur leaves for bugs. The undersides of the leaves is a favored hiding spot for cannabis pests.

Brown spotsHello everyone,
I have to ask the same question, since that problem is spreading although I give her CalMag.
9 days ago only 2 fan leaves had those brown spots, now almost all of them are affected, especially higher ones.
I wanted to feed her once again and then start flushingWeek 10

Calcium deficiency?Hello everyone,
I need your help once again.
I have just spotted some brown/yellow dots on 2 leaves of my plant.
Did some research and looks like Calcium deficiency, but still wanted to ask you.
If that's a Ca deficiency, should I add CalMag next time I feed her?
Thank you ✊Week 9
