well, you've been in flower for over 6 years....that could be a problem....

seriously, it's much more likely to be a mag deficiency that a N deficiency, and adding N to plants in flower (beyond the minimum they need) is asking to fuck up their flower cycle....try adding some epsom salts to your nute mix...

the real solution is the keep feeding them veg food, and even ramp it up about 20-25% while they're going through the stretch, at least the first two weeks, maybe three that they're in the flower room. they're growing a lot of new material and you have to feed them, or they'll start to cannibalize themselves, then they go into flower with a shortage of N and Mag, which will just make the fading worse.

Yeah if adding N isn't immediately turning those yellow leaves at least some shade of green, then that's unlikely to be your issue because N is mobile and moves within a plant quite quickly. With autoflowers, you typically keep feeding grow nutes during their 'preflower' stage and begin bloom nutes once their stretch starts slowing down and real flowering begins. Giving grow nutes during the stretch phase will also get your plant larger with more foilage to support even more buds later on
