Most annuals do tend to lose leaves toward the end of their life cycles.
Can't figure out what this is and it's killing my plants.

This is TMV. You most likely have an uptake issue. I would suggest, like I often do, to incorporate a Mycorrhizae supplement and be sure to water with no nutes at least every other time, at least. The dirt most likely contains everything the plant needs, but is having a hard time eating. Also, you may want to flush with Florakleen to dissolve salt build-up. Aerate your nutrient solution for 24 hrs with an airstone, and tap water would be just fine. Be sure to pH. 6.5 is the high end of the scale, so maybe try a little lower like 6

Not late in the season.look at all the natural yellowing

After sitting their crop yes. During peak production its caused by deficiencies plain and simple.

Because they have finished setting the mast crop. Changing leaves announce things are done and we are getting ready for next spring. Wait this long with cannabis and hermis will appear most likely, C-3 survival method. Comparing deciduous plants to annuals. You do know the difference between an annual and deciduous or perennial plant don't you?

apparently not,
How do leaves change color?
Trees respond to the decreasing amount of sunlight by producing less and less chlorophyll. Eventually, a tree stops producing chlorophyll. When that happens, the carotenoid already in the leaves can finally show through. The leaves become a bright rainbow of glowing yellows,
Do leaves change because of weather?
Perhaps you've noticed that in some years, the red fall colors seem brighter and more spectacular than in other years. The temperature and cloud covercan make a big difference in a tree's red colors from year to year.
When a number of warm, sunny autumn days and cool but not freezing nights come one after the other, it's going to be a good year for reds. In the daytime, the leaves can produce lots of sugar, but the cool night temperatures prevent the sugar sap from flowing through the leaf veins and down into the branches and trunk. Anthocyanins to the rescue! Researchers have found out that anthocyanins are produced as a form of protection. They allow the plant to recover nutrients in the leaves before they fall off. This helps make sure that the tree will be ready for the next growing season. Anthocyanins give leaves their bright, brilliant shades of red, purple and crimson.
The amount of rain in a year also affects autumn leaf color. A severe drought can delay the arrival of fall colors by a few weeks. A warm, wet period during fall will lower the intensity, or brightness, of autumn colors. A severe frost will kill the leaves, turning them brown and causing them to drop early. The best autumn colors come when there's been:
- a warm, wet spring
- a summer that's not too hot or dry, and
- a fall with plenty of warm sunny days and cool nights.

I used rain water, but got a bad case of magnesium def.
This grow,I've used half rain/tap water together now, and r/water exclusively for mixing with liquid fertiliser.
Plants seem to be liking the new regime....

Chuck, you really are an idiot. Apparently you didn't look very hard... perhaps you should google or bing Robert Connell Clarke and see what comes up.. you could learn a lot from guys like him.
I have done a boatload of research today on the subject of TMV on cannabis. I must say that I was wrong, there are no varified cases of TMV on cannabis... but there is this.

I've been going over some of my research papers today and some of the plant/leaf damage looks as though it could be caused by broad mites. I really hope that's not what you have.

I'm not too full of myself to admit that I was wrong, like some suggest. I don't mind being wrong, that gives me an opportunity to learn new facts... too bad Chuck and Alexander didn't have those same facts.. they could have enlightened us on the subject, instead of resorting to calling names and telling people they are wrong with no proof.
I've read many studies by Robert C. Clarke, he is the world's foremost Cannabis botanist. His papers are a good read, if you can understand what he's saying, and are full of cannabis information of all kinds.

you were wrong because I was right, so WTF do i have to admit too? How am I the idiot? You were wrong, seems, you are the idiot,lol
if I were to see a DR. in front of his name, or a university study by him, but nope, nothing.
I guess he is all wise, because HE and NEW member guy2high says so.

You really act like a little kid, Shmuck. It's not TMV, it's HMV.

Still don't see any Professional credentials, ANYONE can write a book, doesn't make it fact.
But besides that, your point is that in nature a plant yellows and dies, well, guess what, we don't grow like they do in nature, IDIOT!!

it's NOT hmv either, dumbass you call people names then try and say they act like a kid, that's fuckin rich
BTW, that is the usual response I get when i prove people wrong,lol

every pic of HMV look just like broadmite damage, Except one which looks like a king louie I have and it is just a trait, OTHERWISE,every plant in my garden would be infected right now.
