Better pics doesn't mean giant file sizes and a lot more of them but natural light or a 5000K LED bulb is real close and shows truer colours and turn off the blurple.
Some of those do definitely look like low iron. Very typical yellowing from from the petiole working out to the ends of the leaves on newer growth.
Waht are you feeding them and what are they growing in? Most garden centres sell iron for plants and it's not expensive. Decent Calmag has iron in it too but at this point you'd have to use lots so a supplement may be better. I use iron tablets and other things and grind some up in my mortor and pestle once in a while and give it to the plants. Zinc, selenium, B-1, Vit C, (ascorbic acid) and a bit of citric acid too.
Look good otherwise.

Hard to tell from the pics but often the new growth is a lighter green from the rest of the plant, and that is normal, if you have just flipped to flower 12/12.
Take a photo in the dark, just after lights out, with the camera flash on.
looks fine, nothing too troubling
http://flairform.com/products/additives/cmx/ at half strength generally sorts out all nutrient issues if in doubt

They look fine to me, the leaves could be a bit better but at this stage still pretty healthy , Id look at adding a half strength dose every second water of http://flairform.com/products/additives/cmx/ from now on till finish. up to you, and do that with your next grow start to finish, half dosage every second water.
This pic was taken a cpl days ago. LA Amnesia in my 2x4 tent. This happens most of the time with my plants. Especially if I just topped a bunch. Happens during first week of flower most of the time. New growth comes in yellow but healthy an they take off. This is day 2 flower. I had to top her a bit bc top growth was damaged. I had cobs too close. Now I have her under an Optic LED Slim 320. I asked about this before but never got an answer besides maybe iron deficiency. I always attributed it to rapid growth.

Yeah its normal after moving to 12/12 ...they come right ...after the stretch phase. CMX will help in faster chlorophyll recovery, but its just a rapid explosive growth and hormone phase in the plant, with the sudden change and growth.... it takes a week or two for the chlorophyll to buildup in the new growth .
nothing to worry about and it normal.
Well said. Appreciate the explanation. Now I can share this info with others.

This something that happens more with scrog, bending , supercropping, and heavy tipping or topping, multi branches , the plant hormones are spread very thin,too thin, if you don't have multiple branches this doesn't happen , if you keep your main limbs to 4 -6 and remove the rest this wont happen, its a sign your spreading hormones too thin, i recommend not using scrog and focus all energy on 4-6 main colas, for bigger better quality bud, less trimming, better yield and quality for time taken..
This seems to make sense. I’m not sure I’d get better results in a grow tent if I did not scrog. I like to grow one plant. Fill out the entire space. One plant equals less work.

These are a few of my non topped plants with just 2-3 weeks veg, give it a try. its much faster with less work, these are just in a 15cm deep tray.
They start like this
You wont know until you try. no training at all. just water them.

Nice looking plants.
I don’t go crazy with scrog. Just use it to spread the plant out a bit. Top her a bunch. Multiple plants an multiple strains is too much work for me at this time.

I've had a single plant in DWC ScroG with a couple dozen branches tied down and literally a 100+ colas on it and never witnessed that. Never heard of that in all the thousands of posts I've read over the last 10+ years in forums either. Not saying it's not a thing but it's not a thing I've ever noticed.
My one plant DWC ScroG from years back. Train wreck x White Widow. 8 oz of dry bud and the same in popcorn and sugar trim. Best single plant yield I ever got in 20 years.
