Its a bug infestation by what i saw in the first couple pics.
Some ppl might say uv lost ur plant but there is a way to rescue it but only if you have a spare room with alot of ventalation there stuff you can get in an aresol can some kind of bug bomb but uneed to be able to separate the infected plants neem oil is another thing but it can affect the buds. I hope am wrong but am pretty sure i saw spider mites in the first pic.
I congratulate you! I also recently raised my first crop of marijuana!
If you have bugs & are growing in tent which you can shut tight, which is in a place away from pets/people (in other words: not in a living area), you can put up those hot spot hanging insect killers. They won’t hurt your plant, and you won’t have to worry about spraying your buds with anything.
Can U take a pic in natural light?
This is the one in late flower now?
No this is new 3 weeks old plantie
It almost looks like pH fluctuations. If it is only on the one leaf I wouldn’t worry about it but if it is affecting more leaves then we need to take a closer look.
It looks like the start of i think potassium deficiency have a look at this it may help you identify what is wrong.
