What are these leaves trying to tell me?

Your plants are looking pretty good.
In the past dudes just called those colors "The Fade" and didn't worry much about it. Like fall leaves, it meant the end was near.
Lately people we identifying this as a Micronutrient Deficiency. Probably low levels of more than one of the minor nutes like copper or manganese or something. Which is what you would expect near the end of your grow. Especially a soil grow, without "full spectrum" nutrients.
Your plants look very green and healthy otherwise, so I doubt it's a lockout issue or anything like that.
Are your plants in soil or something else? How are you feeding them?

Yeah, molybdenum! One of the weird ones.

I'm I'm coco coir/perlite - 50/50ish mix in fabric pots. I'm feeding with flora nova bloom (3ml/gal) and botanicare cal/mag (2ml/gal) in tap water. I add recharge to this mix here and there. So this is just a signal she's almost done?

Well, it's a sign of a particular deficiency, that usually happens to me near the end of flowering. So I associate it with plants being nearly done. But I grow in soil, it's normal for stuff to run out near the end.
In your soilless mix, with the same nutrients, you shouldn't be "running out." You should still be getting the same amount of molybdenum that you've been getting all along.
So maybe near the end your plant wants More micronutrients (particularly molybdenum?) than it was using before. If that's the case, think about adding some Flora Nova Micro to your feeding to provide more.
It's also possible your bloom nutrients are still providing enough micronutrients, but the pH of your root zone has shifted and the molybdenum is just locked out. But your plants look good, it doesn't look like anything else is deficient or locked out.

i like this chart and according to this it looks more like chlorine deficiency than molybdenum

Fairly certain it's not chlorine deficient. I feel with tap water and always have. I can smell the chlorine in it lol

Here's a few shots of my other girls. Looking all puurtyy. Lol. Few small blemishes here and there but overall look good. I think you guys are right. Does the color fading like this always happen?

Potassium (K) deficient is possible.

They were late in veg. And then again a couple weeks into flower. Some sites kept coming back so I left those. So yes it was. But there's still some small sites here and there down low.

K. So all the color change is up top yes? If so that is immobile nutrient issue.
If it is also on the bottom the you have a mobile nutrient issue.
Figure that part out and you can cut the possibilities in half.

It's not that uncommon. Even if there is chlorine in the water you are feeding if you have locked out some micro nutrients then the plant won't receive them.

Just double checked. Nice and green and lush down below. This coloring is only up top.
