Easy now, I just answered your question in your first post as best I could with no information about your grow You have to have a little patience in this game. Sometimes it might take a few days to get an answer. Not 2 hours.

Sounds like y'all are talking about some sort of pH CalMag thing. Yeah? Was info posted about the grow? Can you post a picture of, maybe, the bottom half of your plant?
My guess is a bad case of leaf septoria. Please forgive me for going outside GWE. You're well along into flowering so it could be something pH or nutrient which are common things.

Check this one, too. The ILGM site was showing advanced. The GWE site is less severe.

Yeah it has the light yellowing on the bottom leaves but it has rust spots on them so I don’t think it leaf septoria it doesn’t rub off I think it a calcium deficiency or lack of not sure about how to troubleshoot this situation I just flushed and my ph was 6.2 and my ppm was 766 I don’t know if it is a good ppm or not cuz it’s in 2 weeks of flower it has purple stems on the leaves that have the rust spots on them so I am leaning toward cal-Meg is what I’m thinking but i really don’t know just trying to figure out how to get it fixed lol anyone know what the ppm is supposed to be for run off in soil in it 2 week of flower almost in to the 3 week

Then go with it. The CalMag, I mean. Mine is one opinion. Those Puglover1 and TOKABIGONE fellows seem to know what they're talking about.
If you are not familiar with late stage flowering, which 3 weeks is not, you might get a lot of issues with discolored leaves. Don't fret. It's a maybe thing and common.
But I'm still going with septoria as a symptom because I've had it and because I've done volcanic amounts of terp crystals, in the day, and I'm feeling rebellious and terpy.

It does look like septoria, after looking on GWE. Jay had a nice-looking first harvest, healthy leaves, put my puny summer autos to shame. He was wondering why the small buds (before these spots arrived), I need to read about his strain. I've had a headache banger from hell all day, put a banger in my bong stem, used whatever was on a silpat and it helped, for an hour. I know I have a little bit of some illegal extract that my nephew picked up for me, off to hunt the cupboards.

I mean I don’t know what it is or how I can fix this plant if you have had it before what do I need to do to save my plant and fix the problem if you don’t mind me asking I keep my grow area clean and the only thing I did was add cal-Meg 2 days ago and then this happened so I don’t know what to do but if you know a way to save this big plant I would do anything

I pluck and use a spray of 2 teaspoons of apple cider vinegar and a quart of water. Spray, let it sit for a minute or two, give the plant a good shake to get rid of most of the spray, repeat once a day.
The links I gave you should also have good info on treatment.

Jay1245 I did an experiment where I sprayed a bud with the vinegar spray I mentioned. I sprayed every day for the second week before harvest and stopped the week before. The week before, I sprayed with water, twice. The bud was shaken of excess and kept in good circulation to make sure the bud dried. The final flower had no hint of ACV.
I repeat that this is my experience. If you give it a try and you wind up with pickled weed, 't ain't my fault. And a repeat on circulation. A lot of problems can be kept at bay or overcome with good circulation.

You'll be fine. The plants are well budded. Keep circulation going around your plants and you will have less likelihood of recurrence.
A lot of people do a defoliation in the third week of flowering. You're a little late but still have enough to get some grams.
