I don't know man ... wish I did.
Seeing the whole plant and leaves though ... it does not look like bug damage to me. If it were pests you'd be infested by now. They'd be everywhere.
Fungus gnat larvae eat small root hairs. Adults don't eat at all. Just breed and die. I've had fungus gnat infestations without that effect on plants.
Spider mites leave webs. Again, you'd be totally aware if you had them. Very easy to spot.
Whiteflies could spread disease but not at the pace you described. They love my apple tree but I always get a good harvest.
Grasshoppers would be eating the leaves down to nothing.
What I see are veins and stems that are discolored, and parts of the leaves are necrotic.
I wanna say rust or something fungal.
I would remove the most affected leaves and trash them. Do not compost them. Then watch to see if the remaining ones hold steady or get worse.
How are your stalks at the base?
Also, split a fan leaf stem down the center with a blade. Is it still fibrous inside or are the spots turning to mush.?
What strain is it?
Good news is they don't look dead awful. You should still be able to reap a harvest, though maybe reduced.
If it goes south, try to keep the best leaves/buds clean and healthy as long as you can. You got trichs developing so she's doing what she's programmed to do. Remember, at this stage the plant only wants to flower at the expense of everything else. So it's not going to expend energy for leaves it doesn't need.
Oh also ... easy on the fungicides. They mostly work as preventatives. Which will help the unaffected leaves. But you don't need to overdo it or spray the affected leaves any longer. Better to pinch them.
