Please help diagnose.

So in the past couple days I've started seeing these spots and I'm not sure why. I haven't changed anything about the watering schedule or the amount of nutes I'm feeding them. This plant has been my healthiest and the buds on it look great. Is this something I should worry about? Thanks for any and all advice.

I don't know bro or buds look good from what I can see

how long into flower are ya? and how dem temps be a lookin mon?!

8 weeks into flower. 75 degrees Fahrenheit during the day 60at night

Everything is monochromatic. Shut off the grow lights for a couple secs and shoot regular pictures so we can see the damaged areas.

CalMag....

Can't really see color which would be nice. Turn off the HPS and take some clearer shots and that would make it easier to help. Peace

Here's some better pics.

Maybe not better but out of the hps light. The last one is probably the best one showing what I'm concerned about.

I use a nute kit and follow the recipe. I'm not sure what u mean when u say CalMag. Also this just started and up to this point she looked really healthy.

those buds look pretty swollen, are they fairly close to being ready for harvest? The fan leaves will naturally start to change color at the end of the plants life. Just think of it as if its fall for your plants

I would cut those fan leaves off and leave every thing alone as long as the bud is healthy your looking you all good. I know a lot of growers that lose 25 % of leaves like you are gona . no biggie, quick tip when you start to flush , cut every leaf off so all the buds are exposed to the light better more sugar on the buds and light gets to the bottom

why cut the leaves off? they till serve a good purpose. see if this chart helps.

I don't see one on the chart that resembles what I have going on. But this is a great reference!!! Thanks!!!

KOA330... you are 8 weeks into flower....
Your plants are getting completed...
This is what plants look like when nearing an end...
The plant is using up all it's nutes, from the whole plant to make and fatten the buds...
Those leaves are done... They are not helping plant if they are dead... leave till more dead...
Buds look good...
Just a little 'N' needed, you prob been feeding her with lower "N" of the NPK... right ?
Leaves need more N till the end... to stay green. Now if you are giving plenty of N, then you tell us, read your plant, what did you do, five or six days ago...
My guess, is you have always pulled those leaves on your past grows...before the leaf looked like that...
Good Luck man... I say:
LOOKING Good!

looks like classic nitrogen def to me, not somethign to worry to much about at the end of flowering. dont pull the leaves off though, your plant is eating them for there stored nutrients and ripping them off would just make more leaves turn yellow. when they are no longer of use to the plant they will fall off naturaly

Get yourself some Calmag looks to be a bit advanced so the typical 5ml/gal my need to be upped to 10ml/gal but be careful and test your ppm as calmag will raise it quickly.

They are fine some strains do this at the end of flower. The 12/12 light cycle fools your plants into thinking it is the end of summer/fall time of the year and this is what non evergreen plants do in the fall if you where only a couple weeks into flower this would be a issue but you are almost ready to chop so no worries.
