Very yellow plant!

[MickyPolau]

I have a massive problem with my biggest AK, he changed from begin Very green to this color in about 7 days. Prob I gave him wrong dose of nutrients.
Strange because I give them all the same dose and only this one is showing these deficiency.

Any idea how I can resolve the problem asap?
Thx

How old is that plant.Looks like it's peak maturatey and yellowing leaves are normal.

She looks as though she is supposed to go longer to me. Buds dont look that full to me. Pretty sure someone will come along and give you a hand. I myself is still learning about different problems the plant has. I dont wanna give any miss information. Good luck with getting her back to strength

Plant is 8 weeks at the moment, so not ready yet. I think she is supposed to go 2-3 more weeks.
I have three other Ak 47's that looks much better tho, the bottom leaves are becoming more and more yellow, but this plant is yellow from top to bottom!
Even the top leaves start to be yellow, and this all happened in one week..

well to me it looks like nite burn because your leaves tips are curling down and turning brown. What I would do is check the soil ph and then if its to low flush with some higher ph water to clean her out you might be suffering from nute lockout.

And even though there all the same kind of plant they coud be different phenotypes wich may explain why the others are taking it better.

Hey mickey

What have you tried so far to fix it?

What are your nutes and what amounts do you give of each to the plant now?

 

[Muddy]

How's your pH? Could be a nute lock out situation if the pH is off.

Th for the feedback lads!
I checked my run off water and the Ph is actually between 6 and 6.5!
That's a dissapointing result for me because now I still don't know whats wrong.
I took some more pictures so you have a close up on the leaves.

I checked JM's post https://www.autoflower.org/f7/self-diagnose-your-plants-basic-deficiencies-list-11.html .
And if I understood good it must be an Iron deficiency.
The vains between the leaves are white so it must be Iron Deficiency.
Because my run off water is yellow, it is possible that my test is not acurate because I have the liquid test.
But Im not sure if the colour of the water is affecting the liquid in the end.

I also add some pics of the buds cause they start to look verrrry good, and it really hurts to see the plant dying!

Looks like nitrogen defieciency, or iron,give it a shot of nutes with nitrogen and iron and see what happens.
