Hey, I know that in the final weeks of flowering, the leaves can turn yellow, but it looks like they're rusting. I've done some research online, but I would still like a personalized answer if anyone feels like responding. It's my first plant!
You've got a potassium deficiency imho.... usually brought on by your PH being out of whack.... I'd flush the plant well (with a dose of your nutes in the last gallon of ph'd water) and then keep your PH between 6.0 and 6.5... watch your plant for the next few days, the problem should start going away. If you don't have a PH pen - get one! For my money, it's THE BEST investment you could make when growing cannabis... you will avoid so many issues with one.
Good luck!

Thanks for the answer!
Yeah, when I read my question again just before you replied, I also realized that it probably has to do with the pH value.
Thanks to you all for the responses!
Yeah, it’s hard to explain. It started a few days ago, and today I couldn't honestly ignore it. I'm not really worried, but I'm still curious about what it could be because the next 8 plants are on the way. My grow conditions are pretty minimal; they only get about 10:30 AM to 3 PM of direct sunlight - balcony grow.
That looks more like root issues. As die off doesn't normally look like that.
Without a diary. Hard to c what u talking about.
But fade is fade and can look like rust. But what you v have isn't fade or end of life cycle.
Good luck.
