Im no good at diagnosing problems so don't take what i say as gospel. To me it looks like they might of needed more N during stretch and its now an old issue.
You are too modest mate, i've read your grow diary in the past and if i can grow half as good i'd be happy. Yes going by all the deficiency charts i was thinking Nitrogen too, but what got me is the leaves went yellow in the middle of the plant not the bottom or top and they went yellow fast. Other leaves on the plant are fairly dark green and not pale. Also the whole leave didnt slowly fade to yellow, it started from the tips and worked back.

It looks somewhat deficient, magnesium maybe..?But with the tips burned it’s almost certainly got excessive something, I’d guess phosphorus, now it’s struggled to take in magnesium and iron properly. If not this, and your ph is good it’s going to be from to much fert so I’d back off a smidge
Ok interesting thanks mate, i will do a Google on this condition. Some of the leaf tips are curled upwards like the charts say for Magnesium deficiency. Tricky it kind of matches a few things. I've been using Bio Canna Vega and now Flores since flower which isn't too strong.

Maybe on the 2 least productive plants i can flush one, and give the other a higher nitrogen and see which bounces back and then apply what works to the others.

Hard to say but I wouldnt waste too much time trying to isolate the issue, just flush the shit out of your medium then go in with a good known nute mix
This is a great idea too, as for the known nute mix it's my first grow and i'm a few weeks in to flower so i dont really have a goto mix. I'm using Bio Canna Flores which is 2.5-2.0-5.0 and feeding about 3/4 the recommended dose so thought this was a good safe mix.

So it's a mystery, maybe i forgot to ph the water and fed them 8.2 right from the tap... but i dont think i did.

Never tried Bio but used Canna Flores for years I doubt its that. Something went wrong if you using any additives stop them lol. Could be ph

Only a light dose of CalMag weekly... Just when you think you got this shit figured out, along comes mother nature with an upper cut lol :D

Hopefully i can revive them, thanks mate.

Would you want to crank up the nitrogen tho that far into flower ?

Hey mate it’s usually ph that causes problems, how exactly are you mixing up your nutes?

I've used those exact same trimmers, man i don't know about you but they ruined my hand after a long trim session haha not very ergonomic.

Went super blunt quick too

I dont know... if they are deficient in N then giving them just enough to counter the deficiency might be ok. I will have to read up on how it works with N this far in flower.

I've got 2 tents, both in flower with one about 3 weeks ahead of the other and a few plants in each are showing yellow. I fill both tents water jugs at night and drop the air stone in it. Next morning i check PH and add a PH down to get it in the high 6 range, then that night add the Bio Canna slightly less then recommended dose. It generally brings down the PH in to the 6.3-6.5 range, then 15 minutes later i water.

This may help mate. Pretty sure was originaly done by Jorge Cervantes for a book/growers bible that was banned here before the internet came along in its current form. I have done 3 postings but am leaving. Good luck to all. https://i.redd.it/qhrj8qmjl7az.jpg
Cheers, that's an excellent chart for sure. Though sometimes things dont exactly match, or match a few things so it still takes a bit of experience to come to the right conclusion.
