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 :bigjoint:

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?.

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.

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 :wall: .

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
