I understand. Thank you guys for help. I'll make some updates tonight or tomorrow.
Last time I was watering her I added just terra flores. As I can see , that deficiency didn't progress, which is good.

Do you also think I should ditch everything else except regular flowering feeding formula? I use Canna terra flores 2-2-4. Also I have one 3-5-7.
Which one is better? Opinion?
I think it's too low, because it looks like magnesium and calcium are locked when pH is that low.
I was thinking to water her next time with , let's say, 7.5pH water so I can rise pH in soil. Will that work?
I have a probe and also I fill 1/2 of cup with soil from the pot and then mix it with 7.0pH water, then I mix it and let it sit for 15 minutes. After that I use pH meter to measure that. Also I measure runoff pH. So it's around 6.2-6.4.
I use terra flores canna flowering 3/4 of recommended dosage, phosphorus plus Hessi 1/2 dose, bud candy 2/3 dose, calmag every second watering 1/2 dose, bacti every second watering.
But as she is in late stage, I think to stop using any of those, I will water her with plain water for two weeks...
I just watered her using 7.0 pH water with some nuts. We'll see what will happen' .
Is it possible that those leaves will get back to normal if K is unlocked or added, or they will stay like this until the end?
