brown spots are scaring me now

P.S. - What have you done since your previous 2 question to improve the situation??

Many issues...........leaving it this late before asking for advice is now too late.........nothing you can do now that will fix anything before harvest maturity. And without a diary and knowing what you may or may not be doing, giving meaningful and specific advice is almost impossible. Looks a lot like both potassium and phosphorous deficiencies, but could be a few other issues as well (generally under fed its entire life?). However, it is basically too late to do anything that will improve the situation.

If you're near harvest, like a week or two, I would not worry. It looks like she's finishing up and taking whats left of Nitrogen from the fan leaves. Black spots could be a lack of calcium but again if she's finishing her flowering time....don't worry.

Hard to say for sure without more details, but from the photo it looks like the plant is in late flower and showing some natural fading combined with possible nutrient stress. The brown spots could be from a deficiency, pH drift, or just the plant pulling resources from older leaves. As long as your buds look healthy and no mold or rot is appearing, you're probably okay. Just keep the environment stable, check your runoff pH if possible, and avoid big changes this late. If it gets worse quickly or spreads to the buds, update with more info.

Blah blah blah no diary therfore nonone can say anything because it's all opinion based, 🙄 😒 😉 😴 😑 😏 🙄. Black spots never good, possibly early root rot. Black splotches on leaves can be a sign of nutrient deficiencies, particularly in nitrogen and potassium, possibly iron too. Given it symptom presents as immobile if it was nutrient based alone, I'd guess iron deficient. Tips look to have taken a little EC damage from osmosis. This means salt levels are starting to get high in the medium. You need to get a full ph and ec of your medium along with creating your best attempt at a diary with the correct metrics for your environment. If you want help and continue to ask such questions without taking the time it takes on your part why the fuck should we give a fuck about your grow. Have a lovely day.
