What is the problem of my plant? Flowering stage

[k4n4m3s]

Hello everyone,
I have a plant about two and a half months old - Dark Auto Purple that is currently in the flowering stage.

In recent days I have noticed a strange phenomenon in the FAN leaves.

Remarks:

I use Flora Series fertilizers and add CalMag respectively.
I balance pH 5.7-6.1 every day.
Total PPM:
1000-1200 approx

Tent: 80 * 80 * 160
Water temperature (Celsius): 23-25
Room temperature (Celsius):
24-28
humidity:
45% -65%

My pH meter for the last month and a half has been properly calibrated.
Every month I recalibrate it.


Unfortunately, in the first month I used an uncalibrated PH meter.
I also uploaded a post on this topic and solved the problem right away (after a month of noticing plant development problems), I guess the slow root development is due to this.

Could it be that the current problem with FAN leaves is also due to the fact that in the first month the PH was unbalanced?

I checked a bit online, found a relevant diagnosis.

Is this an accurate diagnosis or not? Thank you.

pic 2 looks like a Ca deficiency to me.

but you pH is in range and at 1000ppm and adding cal/mg you shouldn't have any deficiencies.

you sure your pH is accurate? calibrated it recently?
how do the roots look?

First you aren't likely to have Septoria but all noobs look at it that way
And second there are about ten thousand "what is up with my leaf" threads
So maybe a little more research and since only you know what you have done to them
you can try the search feature
You can find the answer

It is an old story

i'd never heard of septoria. the other one is "is this tobacco mosaic virus on my cannabis?"

start with the simple things. more often than not, that's what it is

Yeah then some guy on FB puts the fear a god in all these kids saying his plants got it from the seed breeder (insert competition here)

Hey, thx for comment.



As for noob jokes, I do not know how effective your bites are for beginners that rly tried to explore and learn in riu

those roots are kinda small for 2.5 months. they look ok though.

how about your pH? you sure that's accurate?

i would maybe let it go b/t 5.5 and 6.1 instead. maybe another nute that needs higher than 5.8 is blocking the Ca?

yeah really small roots,my thoughts are same,feeding that high something is blocking the Ca.

Reduce ppm by 25%,let ph swing to 6.2 before dropping back.

Why are roots so small?

i doubt it.
Ca spots like that usually happen pretty quick. similar to Mg deficiency.

UPDATE:

I assumed the problem was in the water, so I switched to R / O water
170PPM

I added CalMag and fertilizers.

1150PPM + -

PH:
Trying to balance it to 5.5 every time it climbs to 6.2 but that almost never happens, maybe once a week-a week and a half

The problem seemed to have passed, but after a day the yellow dots appeared again.
