New Grower Leaf problems..!

[ukvaporizer]

Hello all

Hope everybody is having a good wkend, i am watching some olympics on tv and having a steam up on my vapor bong.
On a more serious note i am having some early signs of ph/nutri problems
My early self diagnosis is too much nitrogen and to little potassium but i am not sure.
1st pick is middle fan leave very green with tip yellow.
2nd pick is lower leaf pale green and paper like burnt/dying badly!?
Assuming i havnt bolloxed up the file attach..lolzz

Any help with this would be greatly appreciated.

Regards
Rico

PS. I am in all mix soil with a basic rabbit poo tea for feed. day 30. fed only 1 time.

The burnt tip is probably from over feeding, the other a possible P deficiency. But the first thing to look at is your pH. If it's off it could be causing a lockout. A picture of the whole plant would also be helpful. So the first question, what's your pH reading? Also, how old are the plants?

Hi Muddy

I have been checking water in at 6.3 but i havnt checked run off yet.
I will water again and check run off and also get a pic of whole plant up.
I have 2 Plants going at the mo a wembly auto and an auto mazzar thay are both at 35 days approx, the mazzar is the poorly plant the wembly is fine and dandy..both strain grown and fed the same way, i have just moved the wembly ouside as it is massive.
Thanks for the quick response guys....:smokebuds:

Good Evening

I have taken some extra pics of the poorly mazzar and also taken some of my newly outside wembly for interest.
I have also given the mazzar a flush tonight, the ph in was 6.2-6.3 and the run off was 6.1-6.2
The pics are as follows
pic 1 mazzar burnt lower leaf, pic2 mazzar bush,pic 3 mazzar yellow tips, pic4 mazzar burnt lower leaf, pic5 mazzar whole bush pic 6 and 7 are my wembly auto same age and routine as mazzar untill two days ago when i put her outside due to space issues.
Hope this extra info helps the diagnosis, doctors! :smokebuds:

Hope your all having a good evening..i know i am...

Your run off is a little low but certainly not to the point where it would cause a lockout. I would just up your feed pH to around 6.5 and you should be fine.

The problem does look like a P deficiency. What are you feeding and at what strength?

 

[ukvaporizer]

I have only fed the mazzar one time before i noticed the burnt lower leaf, the feed was a weak rabbit poo tea with half a tsp of molasses, the tea strengh was 25grams fresh rabbit poop in 2litres of water so not strong.
I think the nitrogen has built up and is causing the tips to yellow, but cant be sure about the p deficiency as i am a total noob with the autos.
Do you think i should try to raise the p muddy?

Those are not the symptoms of excess N. That would show a deep green color and the leaves folding down on themselves and curling under. That looks like classic P deficiency, so yes, I would up the P. Also, raising the pH a bit will help. At 6.1 your right on the edge of where P starts to get locked out.

Thank you muddy...i realy appreciate the quick responses.....I will raise my ph up to 6.5.
Do you think i should continue with feeding the mazzar and is there something i can give it to raise the p up if needed?
