Help diagnosing the issue in flower

Hi Rollitup gang, long time lurker, first time poster.
I tried searching trough the forums and YouTube and can't get my head wrapped around this one, any help would be very appreciated.

My Grow is from seed, FEM Cheese Diesel by Humboldt, and for some reason one plant is showing deficiencies, or excess, and not the other one.
Same nutrient line, same feeding schedule, different seed. Can someone help me determine what is wrong with the poor plant. I'm in week 4-5 of flower.
It's a soil Grow in a 5 Gal Fabric Pots.
Soil-Mix-Pro/ Mixed with Gaia All purpose 4-4-4, Worm Castings, Perlite.
RO Water amended with Drops Of Balance.
Recharge- (stopped in second week of flower)
Gaia Green 3-8-5 (Top dressed at 1st week of flower per instructions)
Compost Tea every week 5Gal: 2 Cups Worm Castings, 1/2 Cup Seabird Guano 0-12-0, 1/3 Cup Kelp Meal, 1tsp Fish Sh!t, 1Tbsp Blackstrap Organic Molasses.
Saponin, Quaillaja Extract 1/4 tsp per 5 Gal.
I'm watering every second day with 1/2-1 Gal of water, extremely slow so no runoff, (sometimes every third day depending on the weight of the pots so I don't overwater).

Humidity is at 45-50, Temps are at 75-81F, DLI is at 45-50, VPD (with leaf adjustment) 1.1-1.3.

Please help me out or guide me where to look for help, Girls are rapidly going yellow and I don't know how to address this.

Thank you fellow Growers!

Healthy grow

doesn't look too bad to me bro.

I second Big Bud Man, your plant looks very good to me at week 4-5 of flower. Nice grow!

The one with yellow leaves looks pretty hungry to me. Maybe give that one a little extra food on your next feeding other than that they look good

Thank you, I will update as I go.

Thanks! Fingers crossed and it's just a Feno that looks like that when growing, it was like that since VEG, I didn't want to overcorrect with nutrients but it never actually corrected itself, just continued going yellow.

That was my thought, it looked like it's N hungry. But nothing helped. I added small amounts of Recharge since it has Kelp but it bounced on the lower leaves a bit and then went yellow again. I fed them with 3-8-4 Bloom yesterday with a full watering so let's see in few days, I will make sure to post.
edit: Thank you for your help!

For the yellow one, I would not hesitate to water with some Alaska fish 5-1-1 at least once, then again a week or two later if the yellowing has not slowed down. The plants around it look just fine.

I'd not be so sure that it's nitrogen that your plant is missing. If it were veg, I'd lean into some nitrogen, but in flower... I'd be surprised if it was I'd be looking at something that was 0-10-10 and see if that greens it up.

Id hit the yellow ones with a one part bloom nutrient(salts) 1/4-1/2 strength through till harvest. Sometimes you just get a heavy feeding plant and the organics just don’t break down fast enough. Don’t worry though it’s not like synthetic fertilizer is gonna make it taste different

Yellowing one wants more nitrogen - hence it’s pulling from itself. Nitrogen is still important in flower - cellular health , pigmentation, etc.
Flowering plants still root.

However , you are throwing way too many ingredients into that feed soup. Remember , it’s just a plant.
What other plant needs all of that thrown at it to grow ?

Last thing - throw out any thinking that one type of feed will work on “ every ‘‘ plant.
Each has their needs .

I did notice that the color goes darker after using Recharge. Must be the Kelp helping with Nitrogen. I will try adding a bit to see if the lower leaves recover, wouldn't like to overdo it so I don't end up with a leafy bush instead of dense buds.
Thanks. I will try that. Would Indian River Fish Emulsion be a good substitute? I don't have NPK values on it to tell, but since it's fish emulsion I guess it will be nitrogen rich.

That "every" plant is different is a very good point and I understand that.
Also on the nutes, I understand that it might be overfeeding and that yellowing is a deficiency caused by nutrient lockup. I'm conflicted what to do with that girl. If I already overfed her, I shouldn't throw anything more on her, and it's too late to foliar feed since it's already deep in flower.
Is my best option just waiting it out or adding N?
Thank you for your replies, it means a lot seeing the community trying to help, even if the girl dies I learned a lesson for the next time.

All gardening hit and misses are learning experiences - I still kill ferns.

Fern Killers, sounds like a neo-punk band

I just looked it up, looks the npk is 2-3-1. You could go with that, but that first pic looks like classic nitrogen deficiency, and it sounds like you're feeding it a low-N diet already, so I would go with the Alaska stuff myself.

Looks like it is, I top dressed them for the last time with 3-8-5 yesterday (per schedule) and the leaves already started getting greener hue. I water them very slowly, 20 minutes per gal (it's zen for me to watch the plants and water them, so I take my time), so I guess it helped with the intake. I will get the alaska fish 5-1-1 and introduce in small quantities just for that one plant and update on progress.
Thanks for trying to help!
