Appears to be a magnesium deficiency...

Yeah it's hard to pinpoint it because it's a bunch of different symptoms I'll try to add some Epsom salt and see if that works. Thank you for your help

Anybody know what this is?

I mostly deficienies, the leaves get ugly but the buds are just fine.

You are getting close to harvest, some deficiency is OK.
Not sure if flushing will help.

You can cut off ugly leaves. That makes it easier to notice if the problem is stable or spreading.

Yeah I keep staring at them wanting to cut them but I don't want it to spread to other leaves. I was hoping to take this one to 10 weeks so another 3 weeks. I guess I just have to hope she makes it. It sucks that they always stay perfectly healthy up untill this point then in two days it goes crazy lol something keeps happening in this time frame where I'm skipping something or just salt buildup from all of the fertilizer. I guess I'll find out eventually.

Maybe your flowers are doing so well they are sucking all the nutes out of your fan leaves?
After the chop lets get a good look at the roots, see if there are any problems that might slow nute absorption.

You plant looks fine for her age. Look at @Corgy's plant that survived on just milk. That is an ugly girl!
Oops, I mean she has severe appearance deficit disorder:

Look at those fan leaves, hideous, but she gave 213 g wet.

I'll remember to post a picture of the roots after I harvest. I might just have to go the KISS route seems to work better!

You are very kind, but I am not battling your tropical warmth and wetness.
My humidity is much lower, around 35%. Air Conditioning makes everything easier.

If you can find a way to lower the humidity.... Clarke says:
"Aridity favors resin production and total cannabinoid production"

"Cannabis seems not to produce more resins in response to dry soil, as it does to a dry atmosphere. Drying out plants by with-holding water for the last weeks of flowering does not stimulate THC production, although an arid atmosphere may do so." -Robert Connell Clarke, Marijuana Botany, 1993

Yeah I tried everything there is no drying it out lol. Even with my 70 pint dehumidifier running constantly that tent won't go below 50. It also doesn't help that I had four plants in there. That raises humidity quite a bit. Idk if I'm battling nitrogen deficiency like everyone says. I honestly think @eggmansky hit it dead on with the magnesium deficiency. It could be just to much calcium or nitrogen causing a lockout in my soil. The whole grow even without nutes I have had a little bit of claw going on so that tells me too much nitrogen and that means a magnesium lockout. But it does continue to happen in every grow right around mid flower. I'll figure it out I just have to keep trying different things and get it dialed in. They start with purple stems and then a week or two later this happens. And my sour blues just got purple stems let's hope she doesn't end up like this haha

Are you running a stable Ph or do you let it swing?

I stopped checking Ph since I'm all organic. Supposedly it doesn't matter since the beneficial bacteria and humates are are supposed to buffer it anyway. I used to ph every feed though and this problem would still occur. It's not just this plant it has been the last four or five plants I have grown. Even when I did check the runoff and up the ph of my feed solution. It definatley could be an issue but I don't see how considering it happens either way. I did check the ph off my run off just in case and it was around 6.0-6.5. It really is getting annoying though seeing has it always happens around mid bloom at the most important time. I don't have any issues the whole first part of the grow then bam! It hits like a train wreck. At first I think it's the feeds but then I see nobody else that uses General Organics have these problems and they have the same feed schedule that I am using. This is my second different type of soil so I can't blame the soil either. Unless I have alkaline soil I know it isn't acidic.
