Desperately need help ASAP pls

My two sweet god girls are just over week 4 in flower. They seem incredibly far behind my strawberry cough and critical kush. I think there is an issue and now that I can post pics again I'll ask for help. As you can see the leaves are curled under and quite ugly. They are in soil and absolutely no problems with my other strains.

my plant seems to be doing the same thing...
are the leaves hard and brittle?

They are harder then the healthy plants leaves for sure but they don't fall apart on me. I was thinking it was sulfur issues but I'm starting to think otherwise and I am in dire need of help cause they need to come down in 3 weeks more tops ideally :s

my issue is more than likely due to the 1 big ass sativa dom I'm growing is hella close to the light. Completely grew past my expectations and my height goals. Grew to much basically and I cant raise the light anymore!
But sulfur can cause this too?

As far as I know it can but I'm not sure at all lol. Heat stess is much different looking and you will be able to see very noticeable burns.. Any pics! Maybe I can help while I await help myself lol

Ph issue to me or over nuted looks like a N claw, either way a flush will take care of your problems, flush well with ph corrected water and stop feeding for awhile let her recover.

I'm assuming that was directed to me so I'm gonna drop like 4L of water on those two and hope that will help correct it some; thank you
lets see if I can get these girls back to producing some buds damn it
