Yellowing Leaves - Gran Jefa - Day 102, Day 49 of Flower

First time growing.
Gran Jefa from Green House Seed Company
on Day 102 of grow and 49th day of flower.
Anyone got any idea whats going on with these leaves?
Is this normal?
Nitrogen deficiency?
They have been really happy and doing great until now, this just showed up

You only have a couple of weeks to go. It is normal for colors to fade at this point in flowering.

I would offer her a Cal/Mag drink with some food with low level N. I have a 2.4.4 for this reason alone during flower.

Those are some nice phat 9 fingered fans!!

Agree with @MidwestGuy guy. You’re in week 7 of flower with 2-3 weeks left maybe 4. What nutrients are you using and the input and run off PH :love_you_gesture:

Thank you for all the help.
I pretty much water once a week, give or take a couple days, when the leaves droop. sometimes its 7 days, sometimes 5 days.
I learned a little late about cal/mag.
Started adding cal/mag on Day 63 and kept adding until this last watering, which was 0 cal/mag.
Did 1 tsp per gallon for 2 waterings
then 0.5 tsp per gallon waterings after that maybe another 2 waterings, dont know off of the top of my head.
Anyway I think they are good on the cal/mag now.
I am using fox farm stuff and a feeding schedule from a youtube guy
last 5 or so feedings have been
2 tbsp per 5 gallon of big bloom (0 - 0.5 - 0.7) and same of tiger bloom (2 - 8 - 4) per watering ph to 6.8 until I get a solo cup of run off its like 3500 to 5000 ml of water per plant

I just finished 2 Yeti/Wedding Autos they are in the dry tent.




and have 2 more Jack Herer going right now too.
Their leaves seem to have an excess manganese problem from what the charts look like???
So I only gave them water ph to 6.8 this last watering nothing else.

Run off ph for
gran jefa - plant 1 = 6.03, plant 2 = 6.38
jack herer - plant 1 = 5.70 , plant 2 = 5.79
I added lime to the soil 2 waterings ago, 4 waterings ago, and 6 waterings ago, run off ph had gotten down to 5.0 before i started adding lime, had to learn about that on the fly as well as the cal/mag from a my grow mentor

Definitely a PH issue on the plant in the last pics. 5.7 is pretty low and the lime will take a while. You may want to consider a reset flush. Don’t forget the Grow Big on the 1st plant, it’s the needed nitrogen source :love_you_gesture:

Those run off ph numbers were from 2 waterings ago
this last watering 3 days ago
gran jefa - plant 1 = 6.11, plant 2 = 6.23
jack herer - plant 1 = 6.19, plant 2 = 6.21
and the watering 3 days ago for the jack herer was only water ph to 6.8
