First off, welcome here @Deepacx. The appearance of your plant can have several causes: pH problems, too much or too little nutrients, soil too wet or too dry. It would be good to know more about how often you water, fertilize…
Give us some more information about it, then it will be easier to find the problem.

It looks to be deficient in a couple of things. Information about your grow like your watering and feed schedules, medium used, temp, humidity, pH, and EC or ppm will help narrow it down.

It’s been almost 15 days since I’ve supplemented because I was informed that in the last month of flowering I shouldn’t add any more supplements as the plant consumes what’s in the soil and in itself. I don’t know if this is true.
Carolina soil pindstrup
Soil pH is neutral 7.0
Normal soil moisture
Temperature 28-30 °C
Grow tent humidity 57%
Felt Pot 15L prime cultivo
I’m watering every 3 days because the soil loses a lot of moisture.

Feed till the end is my advice. I do it organically and end up with some good bud. Otherwise you could end up with deficiencies that could harm your yields and potency.

Wash the soil, over water the plant let it drain alot of water

Some information is still missing to truly assess the situation, but at first glance, I would assume PH problems, over-fertilization, and a subsequent nutrient lockout. Thoroughly flush it, take it to the shower and let 50 - 80 liters, if not even 100, run through. Afterwards, ventilate the room or the tent well for the next few days, and hold off on watering for a while.
The leaves that are as they are will remain that way. It’s important now to pay attention to the new ones coming in; are they nice and light at first?
Do the new leaves get darker on their own over time, or do they stay light, which could indicate a nitrogen deficiency?
Do the tips of the leaves look healthy, or are they turning white/brown and looking burnt?
I don’t think so, but then there would still be too much fertilizer in it.
I don’t know if any of this helps you, but I’m keeping my fingers crossed. If you like, you can also take a look at my page and classified ad

Regarding mineral fertilizer, I also advise against fertilizing until the very end, but with organic, I use it until the end. I give my own fertilizer up to 3 days before harvest, so with the last watering, I give her a little extra, and then I let the soil dry out for 3 to 4 days, after that, I personally chop her then.
However, your lady apparently had some difficulties throughout her entire life cycle, which, to put it bluntly, ultimately affected everything – sometimes less is more!
Did you happen to create a Growlog for her?
