Looks like severe calcium deficiency. The 91 needs a ton of cal & mag dumped on it to keep her happy. You're kind of late in so I'd avoid any cal product with nitrates in it, Nectar has Herculean Harvest and Demeter's Destiny, neither contains N and are used throughout the flush. The leaves won't repair themselves but the plant will do a lot better.
I wouldn't change a thing...
Worst Chems I've ever smoked are the chems that are over fed....
They're the ones still showing DARK...GREEN...GLOSSY leaves at week 4 flower....
That's the Chem Growers Curse..
She's usually over fed because most identify her by that Dark Green Waxy leaf...and most Chems end up having that Mag burn and taste....waste them sexy girls!
Looks great!

That's true n not true at the same time.... Its a very fine line with chems n to green to much cal mag... They will yellow out quick on ya if not happy early on in flower n not got there potential.. But I agree to much it's hard to flush out n they turn out very genetic green smoke.... I keep my ppms @1.2-1.4max n work the n and cal mag out bout mid flower of everything is lookin like it's supposed to ...
is the SKVA cut a light feeder ??? i normally run 1.5 max in peek flower & 99% of my strains love it at that EC .
but the Chem91 is not liking it at all !!!
theres only 2 91's outa 12 plants on the same rez & everything is great except for the 2 Chem91's .
anybody with experiance with her want to throw some ideas at me ?
the 2 pots closest to the barrel are the 91's ..... they're at 55 days of flower in the pics .

Wonderful!!
anyone know which chem cuts made it to the UK?
For what it's worth here's my run with a Chem 91 Skunk VA cu from the greenhouse this year. She wasn't happy at all needing WAAAYYYYY more calcium I think. I have one indoors right now that just started flowering today, day 1.
