Potassium deficiency?

Auto, 6.3-6.5 PH, 50% humid, 2.3 weeks in flower,
ppm 1000, light 12/12 (maxed out).

Is this a Potassium deficiency or a Phosphorus?
Based on google search I think it's Potassium, but I just wanna second opinion who is more experienced then me.
Thanks for al the info i can get

And yeah I'm growing in soil*

Temps? I'd say heat and/or Potassium. Phosphorus tends to look more splotchy.

The small brown spots are probably calcium deficiency.

The problem with a deficiency is what caused it? Not enough K in your nutes? Lockout from too much of something else? PH too high or low. If you're feeding the plants a flowering formula, those usually have a lot of PK in them already.

The temps are 25c lights on and 20-21c lights off.
Yeah i have heat stress but can't do noting about it, I wonder if i can build a controller for the lights to solve that problem whit that?.
I have meter the water before i watered the plant it was 6.5hp and the runoff 6.4hp i think thats on point for soil?.
It's maybe like you said: the right formula for the plant, I was feeding whit only whit grow and cal-mag, so I maybe need to switch whit the bloom instead?.
I read on RIU thats its okey to just feeding whit grow in plants 1-2 week of flowering and then switch to bloom (BioBizz line up).

Temps are bad. Those plants look farther along than 2 weeks. Once the flowering starts it's time to switch to a bloom formula. Hopefully just switching to a bloom formula will straighten things out for you.

Okey what temp should it be on?.
2 weeks and 4 days in flowering today.
Yes i will feed her bloom nuts from now over ao i hope it's gonna be alright, but should i bump the ppm up to a 1200ppm maybe?

considering it's an auto and you've been feeding at 1000ppm that could be your problem I have trees that are pretty big and they only get fed 800-900. or I could be majorly wrong I'm not thinking so though.

Man my head is spinning as hel right now hahaha i found this:

If I go as it said on the photo im under feeding just a bit whit 100-150 ppms, but yeah it doesn't say nothing about ppms for autos hmmm.
Now is the question if i should feed her some more or back of to like you have it?.
I'm a bit confused because it's my first grow ever and i have noting to compare it whit .

Meant to type "temps aren't bad." - sorry

Looks like K def to me

wow, if your adding that many nutes to your grow, its not tecnikly soil, my soil will last for most of my grow with only a few feedings needed

if your growing soil, you might want to invest in some seaweed solution, it cancels out most every macro nute problems as well as major nute problems

Yeah i have a ALG-A-MIC (BioBizz) that contains seaweed, should i put more in maybe then 1ml per 1L water?
