Confirm my diagnosis...?

[Amaximus]

Hey everyone. Admittedly I am extremely bad at diagnosing my plants. I just don't have the experience yet. You would figure I'd be able to get the chart of deficiencies and just match what I'm seeing to it, But no, I'm having a tough time. So if anyone could just confirm what I think, or help me out with a diagnosis that would be great.

Some shit to help you along... Both girls have been grown 12/12 from seed and are around 50+ days since sprouting.

Soil is some reused ffof (about 25%) and the rest is a 3 to 1 mix of fresh ffof with perlite. (I don't know if this is what is causing my trouble or not but I will never do this again.)

Plants were mostly given straight water tap water left out for 24-36 hours. I began bloom nutes several weeks ago and am supplementing with Cal-Mag.

Also, meter broke so i don't know the ph currently... New one is on the way.

Magnesium deficiency? Started on lower leaves... (Yes it is in a party cup and will remain there until harvest. This plant is part of LED Party Cup Competition. Is it as simple as it being in a tiny container that is causing problems here? I wouldn't be surprised.)



This one has the same exact history as the last plant except she was removed from the competition and x-planted to a 2G smart pot a week ago. A mixture of N, Mg and/or Ca deficiency?




Thanks for any help. If anyone has any questions that might help diagnosing these guys just let me know. I'm on and off throughout the day.

Nute burn. Flush with Ph'ed water two times the amount of soil, let it drain off. She will be back growing nicly in no time, as for the yellow leave just oull down on it that will fix that

Can we see a pic of the underside of the leaves?

Looks like nute burn to me.

Yeah? I wasn't even thinking nute burn but it would make sense. My ph meter broke about ten days ago and I've been slow to replace it. I ordered one but it just hasn't arrived yet. Hard to imagine things went bad so fast. I'll begin a flush. Thanks!

Lights are off. I'll take some photos in about 3 hours and have them up for you. I'm guessing you want pictures of both plants?

I would think you are going to get rootbound sooner or later trying to grow a plant from start to harvest without repotting into something bigger than a solo cup. Just my opinion though.

I'd be surprised if she wasn't rootbound yet. I kid of expect problems with that one. It is kind of the point of the party cup competition. Figured I'd ask on her anyway. It will more than likely be a downhill battle.

 

[monkeybones]

wow guys, fail. nute burn on bottom leaves? do your homework

the plant needed re-potting a while ago. i see numerous deficiencies

 

[dank smoker420]

if you supplement while using tap water would could have an abundance of cal or mag since tap water has some in it.

 

[monkeybones]

shouldn't be cal/mag. looks like macronutrients. P, K

cal/mag does not hurt though

still, re-pot that thing. seriously.

ever see a 16 year old who looks like their parents haven't bought them clothes since they were 8?

 

[spitsbuds]

well said monkeybones. nute burn lol lol.
also op it might be nothing but in the 2nd lot of pics a lot of them spots are on the leafs veins. might b worth looking for bugs to and listen to monkeybones

 

[Amaximus]

I appreciate the replies guys...

Which plant are we all talking about? The party cup plant is staying in the party cup. That is the idea of the party cup competition. That's why I mentioned it. I expect that one to have problems but I figured I'd ask anyway... If everything with that one is strickly related to being in a tiny container then we can stop discussing that one...

My main concern is the girl in the second set of photos...

As I said, I have been giving Cal Mag... And this one was in a party cup and was just x-planted into a 2G. Eventually a 5G or 7G smart pot will be her final home. I'm just trying to get her a little healthier.

No bugs on my plants. None at all... (Literally just checked with a scope after reading your post)

Photos of the bottom of that leaf as requested:



Thanks!

 

[Amaximus]

Oh, And I already flushed...

 

[Amaximus]

I apologize for three posts in a row but I figured since ya's were trying to help me it only made sense to provide ya's with as much as I could.

I just took photos of the next set of fan leave above the real bad ones. The further up you go, The healthier this girl is.

 

[monkeybones]

you should start to see some improvement within a few days with the extra root space

don't let the transplant shock spook ya

 

[Coho]

Glad you didn't find bugs..I was leaning that way.

^^^Those leaves have now curled, dried and are crunchy and look exactly like the the second set of photos from the first post I uploaded.



I really wish my damn meter would get here so I could check ph...

 

[Amaximus]

This plant is getting worse and the fan leaves are discoloring their way up the plant. At this point I'll probably chop her but I'd like to figure out what is wrong with her and see if I can rectify it so if I encounter this again in the future I can do something about it.

All the info needed is listed in this thread... I just want to know if anyone has anything else to add or a new idea what the problem may be?

I'm including double photos of everything, with and without a flash. First is w/o, second is with the flash.

If anyone has questions for me please feel free to ask.







This start out on the lower fan leaves and as they die off it continues up to the next fan leaves. You can see the progress of how this starts out by looking towards the base of each leaf furthest from the tips. Green with orange/brown/yellowish spots/dots to start and then it darkens gets crispy and eventually falls off.

Thanks for any help.

I have not had that. Start looking at diseases like blight.

Thanks Coho... I was thinking a disease of some sort myself seeing as none of my other plants are exhibiting this and they are all being grown exactly the same.
I'll look into it... Like right now.

Anyone else have any insight? Or can steer me onto the right course?

Thanks.
