hi dude ! no you can forget the N issue it s not this to my point of view...
for the GG it s looks more like a Ph fluctuation .....it could also be a calcium deficiency but i dont think it is.... the new leaves on top are not affected.....so i tend to a big problem of Ph fluctuation....(it could also be a problem of roots (rot root) but i dont think so).....

what is your exact soil composition ??
for th CM it s a bit more complicated....i tend for a mosaic virus called TVM ! take a look here -- https://www.growweedeasy.com/cannabis-plant-problems/tobacco-mosaic-virus-tmv
you have to watch the futur evolution to be sure.... but it s looks like a tvm ! if my diagnosis is confirmed for the CM you gonna risk to have a slow grow and a poor crop at the end......
dont hesitate buddy to post pics day after day and mp me 🙏
hope this help
