No I haven't used manure, just soil and they haven't had any nutes. It's happening to almost every plant on every lower leaf.
I just did a PH test of the soil and it's at 8.0, could this be the cause?

yes. it is.

yea it is most likely caused by ph fluctuation. your ph isnt always 8 is it? likely not but anyways alot of nutrients are locked out in high ph. N, MG, I, Z. Its the unstable medium that is causing your plant to do this.

Thankyou + rep
Is it as simple to cure as getting some PH down and just adding it to their water?

yea ph down and flush with it until you get the desired results

run about 2-3 times as much ph'd to 6.5 water as you have soil in the container through it. the leaves showing this may not make it since you cant undo the damage done so the plant will start draining the stored energy and nutrients stored in those leaves out and when she's done with them drop them. So if a leaf doesnt come off with a gentle tug let it be.

That's weird, on the upper leaves they have the exact charateristics of nutrient burn, super dark green leaves with the tips curling and browning. I guess the other nutes you mentioned are vital in transporting stuff around the plant and they are what's getting locked out.
I just did a PH test of my nutes and it's come out as this.

Sorry dude, basically it's dark green as f**k. So basically my soils alkaline atleast 8.0 and my nutes are super alkaline too, can't believe I never noticed it either, I just took a sniff of the nutes and it's like sniffing strong bleach. Best get some PH down tomorrow.
Hope it solves the problem!

It is a dark color, signaling alkaline.
DD has already given the proper advice, so the only left for this thread is a post in a few days of a better looking plant.
Thanks buddy! Finally starting to get the hang of this.

I agree with serapis. Although it I got those same crispy copper burning from using too much CalMag.

Super dark lush green vegetation is a sign of Nitrogen toxicity...
And 8.0? yeah I though that might be it. I think in soil pH is supposed to be between 5.8 - 6.2. Thats the sweet spot

I thought soil was 6.5-7
