Leafs Yellow and Dry

If you're well into flower, it's the plant sucking nutrients from itself to finish up the bloom. I leave them unless they are fully brown/dry, as the plant will just keep moving up to suck more out of the next leaves up. It looks bad, it makes you feel bad, but it's normal once you're into the buds making tendrils, your sugar leaves going crazily snowy and you're praying for landing this crop. My first grow this drove me insane, I've learned to let it go if you're well into bloom. (at least a few weeks).

I'd consider defoliation at the bottom of your plant, for those leaves that aren't getting enough light, as the deficiency in Nitrogen may spread among your other leaves, but if the plant looks healthy. Then just pluck those yellow leaves off. Should help give the plant energy to focus on buds rather than sick leaves. Good luck!

Or you can just leave them regardless and when the plant is done sucking nutrs from the leaf she will drop the leaf by itself, meanwhile it may not have any N so the leaf goes yellow and ultra dry but she probably still has macro, micro and other primary nutrients.

At the cycle end the plant start to yellow their leaves because she sucks the last nuts from there. It's a normal process, my recommendation is to remove them as soon as they go over the light/bright yellow (green -> light yellow -> bright yellow -> dark/brown yellow -> etc.). Fingers crossed for you and happy growing.
