Leaves curling up and diyng out, please help identifying the cause.

[green_blaze]

Hello I got a plant whose leaves are curling up and yellowing and drying out but not too sure what the cause could be, never seen anything like it.
Could this be a phophorous deficiency maybe?

Then there is this other one which looks much more like a nitrogen deciciency to me but would gladly take some advice from the more experienced growers before proceeding. Also if hat is the case it will leave me quite puzzled as I thought I was close to have given too much of it.

Need conditions bro

Need conditions bro

Yeah you're right I didn't say much sorry. Regarding conditions they get lots of sunlight, it's been hot like 80-90 degrees during the day but the evening have been a bit cooler, like 65. they were trasplanted in fairly large holes filled with compost and well decomposed manure. The thing is that another right next to them looks just fine.
Been fertilizing with urine and was planning to start giving compost tea once flowers start to develop.
Local soil is fairly poor and quite basic, maybe they have used up all the good stuff I gave them already? I know the roots have not expanded too much because we had strong wind a couple weeks ago and the one in the second picture started to bend over, the whole root stock looked like had rotated a bit in the soil, so hence the steel pole supporting her.
Hope it's a bit more clear with all this this.

When you say you fertilized with urine. Your not pissing on it or dumping piss on it I hope.

Hope he meant urea

When you say you fertilized with urine. Your not pissing on it or dumping piss on it I hope.

I dilute it 1-10 after it's been in tanks in the dark for a while, same as all the rest of the vegetable garden. The occasional straight piss might happen but it never seemd to upset any plant.
One thing though I remember now, I did bend it over a bit to givesome breathing space to the others as they all grew a bit large. But no visible damage was done to the stalk as I slowly pulled it, over several days. This was about a month ago.
Could this be a bad reaction to that?

Hope he meant urea

To be clear: I piss in tanks, store them for a while, depending how fast I use it, got about 30l in stock so probaly a couple weeks or more, and then I dilute it 1-10 with water and irrigate the plants.

 

[osowhom]

urine is the culprit for sure

 

[beercan]

I would guess your plant is really pissed off then

 

[green_blaze]

urine is the culprit for sure

You sure? It works wonders for all the plant I fertilize with, been using it for a couple years now..

I would guess your plant is really pissed off then

lol


And if urine was the culprit, why one plant out of four is showing such a bad reaction, shouldn't they all be more or less in the same state?
And why only after all these months of veg having grown 8 feet tall they show signs of distress?
Could it may be an excess of nitrogen? But the plant in the fourth picture looks more like a lack nitrogen to me, don't you agree?

Ammonia probably

After you spent all that time pissing on it i would say flush it!!!!

Try shitting in it instead

Damn that shits funny!!

Well piss has a lot of nitrogen in it I have a dog so when he pisses on the lawn I try to go behind him and dilute with water and yes the grass is greener In those patches than anywhere else but bro I wouldn’t use it to feed plants and it looks more like the top is torched is it getting the most direct sunlight ? I’m thinking temps plus piss = torched

 

[beercan]

All i gotta say is if your selling that shit your customers would be "pissed off" if they found out!!

 

[Seawood]

The guy at the grow shop said to give them more P so he did just that. Pissed on em.

 

[SidV]

Ammonia probably

Since op said he uses urine I would go with this also. Ammonia vapors will do that. And just because the others are alive doesn't mean it's not the culprit and if it is ammonia vapors then it's just a matter of time untill it gets strong enough to do the same to the other plants.

How far down the stalk does the wilting present itself? The lower part of the plant seems okay save for some yellowing

I'd guess that there's a breach in the stalk either due to a pest or a fungal infection

 

[green_blaze]

Sorry but do you guys realize urea is one of the most the most used fertilizers?
I use the same urine to grow a 300+ sqare yard vegetable garden with no problems of this kind and know sevral people who have done this all their life.
I seriously doubt ammonia vapors can be the problem, especially outdoors.
The three tomato plants I have in a pot by the green house should be burnt to a crisp as I piss in them WAY more often, at least daily.

The leaves are drying out all the way to the bottom, in fact it looks like the lower fan leaves are the first that have gone.
