seedling troubles! please take a look

[Rob547]

So I started a new grow on 11/6. 3 of 3 seeds (bagseed) germinated, everything was good. Then after about a week or so they started looking less than great. I think its a case of nute burn, and if not maybe Mg deficiency which makes alot less sense cause they're soo young.

They're just past 3 weeks today, pics are from today. If it was just nute burn I wouldn't be so confused, but the other 4 plants from my current grow (1 surviving female is almost done) were planted/watered etc exactly the same as these with absolutely no problems. Also under the same lighting (floros + 2 20w CFLs) Doesn't make any sense to me.
check the gallery and you can see they had no problems

They're planted in 'gardners gold' organic soil, with a little bit of lime and perlite. No NPK on the soil so I'm not 100% on that....

SOOO...if my diagnosis of nute burn is correct...what do I do know? Let them grow? flush?? They were just replanted last wednesday and they have been going through a decent growth spurt.

ICmag infirmary always comes through and all of your experiences and advice is GREATLY appreciated. Everytime I see a problem thread on another forum I send them to the sick plants thread in here.

as you can see the rest is healthy jst the first set of leaves.

Hi there,

your plants look ok. Some nute burn, Correct your PH to 6 -6.5 and water with no nutes.

When u start using nutes again, whenever that is, start using a small dose and increase as the plant grows.

Good luck

Where do you, guys, see any signs of nute burn???

Hi Wolvern,

the plants look fine as new growth is ok.

Maybe there is no nute burn so i suggested the PH correction.

However you can clearly see the bottom leafs going crispy so i assumed some N tox.

I believe if the advice I gave is followed there will be no more problems with this plant.

What would you suggest?

ph should be around 5.6 - 6.0 ..its organic soil..witch means soiless..and plant looks fine...its not uncommon the lose the lower leaves in the beginning...could be irregular feeding ect...

Hi Core,

to be honest i missed the "gardners gold". In this case the ideal PH would be 5 - 5.5
and not 5.6 - 6.

But the actual value has to do with the plant and the medium used (bark, coco, etc). So the gardener would have to experiment in between those values and find the plant's sweet spot on PH.

Hey there Core,

i don't know where this chart came from. Some one made a study on MJ nutrient availability? A university or something?

Also it says Hydroponic and Soil but i see no Organic. Plus there is no mention of the medium.

check out this web site:
http://www.grotek.net/planttalk/article.asp?id=22
Some Dr.Bin Laden supports what i said which i read years ago in an official agriculture site.

Anyway, are you going to give any advise to this guy?
It seems like you are just trying to prove me wrong, when what we say i so similar.
Why confuse the grower.

Like i said Rob547 your best bet is to find the PH that works best for your medium/water PH/Water alkalinity/strain by trying some values between 5 - 6.

p.s. i am only trying to reach 50 posts so i can read some PMs people have send me. This is why i try to help some people. So don't worry Core the knowledge throne is all yours after my 50th post.

EDIT: my last comment on throne was a joke. Please don't think i am trying to be negative. I respect you as a grower since good info is what u seek.
Peace

gL, be sure, there have been more than one university level study on cannabis nutrition.

Hi Wolvern,

i didn't say there hasn't. I just never came across one. It would be very interesting to read it. If you know any links pl provide.

just trying to help and maybe learn one or two things. if you can't find the links no prob. Since you say there are i believe you. I will have a look around my self. I am sure though it will be hard to find. so, any links are welcome.

stay safe

i gave advise...i said to lower ph...maybe you did't notice...but you even corrected me....as for the PH ..i'm not going into a debate with you...i'm in soiless myself and my plants don't thrive under 5.4 ph....

as for ya little joke...don't be condesending dude...i just gave my if you say we saying the same why you go and correct me then?
and get off your high horse ...i don't give a F about your Bin Laden study...

 

[ganjaLeaving]

thanks man. you are the shit.

 

[scegy]

my first thoughts were a little too much ferts and too much water, it's a big pot for that seedling, and u can overwater it easily with that kind off substrate, ROB be sure to check the bottom of the pot and touch the soil(substrate), if it's soaking wet, it's not time to water yet!
you can also take weight of a pot filled with dried soil(substrate) and compare that to the pot with the plant that you want to water, there should be little difference between those two readings if it's time to water

p.s. about the pH, i agree that in soiless range from 5.4- 6.0 is optimum, other than that will cause defficiencies.

core: why is organic soil considered soiless??? from what i've learned in coledge, most organic things in soil happen at the ph close to 7, so it's more in 6-7 ph range for any(there are exceptions ofcourse) kind off organic being or matter, generally speaking, and organic soil is general

i always keep my soil pH at the range of 6-7, or rather under 6.4 to 7, every time i go under that i see issues mostly in the microelements department

but his ph might actually be too high, because of this..

They're planted in 'gardners gold' organic soil, with a little bit of lime and perlite

also in the other hand it could mean that the ph is already too low, but i doubt that because it sounds like some fancy soil that has lime and shit in it already

but, i don't know this particular soil, haven't worked with it so everything is possible, test it for yourself rob, it's the best way to do it

another possible factor, i hope you know how to take ph readings with soil, and that u'r using a calibrated pH ETC., else search the forums for "soil ph testing" and something should come up, i bet it's in the FAQ's already..homework!


good luck!

Ganja, I am not flaming you, but that chart has been around for a very long time, since back in 2003 to my knowledge.....

Another thing, Core is a very respected member around these parts and I Have never seen him give bad advice and we always post in the same posts most of the time...... he knows his shit and gives his time many times over to help out other growers in need; and as for the university thing, yes there is many of them that do studies all around the world; I do not know where the chart came from, but I do know it is very accurate, if it was not then some of my knowledge from pH in certain nutrients would be wrong and the information I give to people would be wrong and I would have people getting very pissed at me.
THere is NO knowledge throne either, MANY members around here gives there time to help out. There is no "one person throne" going around giving out information to people. Even if you were joking about that, I find that remark "rude" really; and I have a great sense of humor, but somehow if you meant that as a joke, I find it meant more as a poke than anything else.

So please do not take what I said wrongly, I did not like the fact you went after core like that; he has been here a lot longer and when you came in here like you did and went after him the way you did, I find that to be rude.

so just giving my 2 cents on the matter,
Sorry for hijacking the thread: OK! Resume discussion about the thread topic!

 

[ganjaLeaving]

No problem MNS.

no hard feelings to you or any one. really. My posting skills are not very good yet in expressing jokes. After i read my "joke" i realized it sounded like a negative thing hence the edit.

Never said that the info is false.

Respect

 

[Rob547]

hahaha thanks for the great debate guys.

I will definitely check the soil, at the moment I expect it to be around 6.5 or so...going by limited experience with the soil. I also realized that now they are in much bigger pots and flushing could overwater them easily. Ill figure out something.

I think organics are considered 'soiless' cause they have peat moss and random shit in it. And yes, my soil does have lime and random stuff in it. 9$ per cubic foot.

One last note, I HAVE NOT given them any nutrients whatsoever, I guess theres just some in the soil that I didnt notice last grow. It will probably be 2-3 weeks before I give them any.

once again, many thanks Ganja, Core and everyone else. my plants thank you too

 

[Core]

np did't wanne stir any shit inhere...thats not my style....Just wanted to advise you on a matter...
just check ya ph of ya medium..but don't take runoff to have a accurate readings...if thats in order i just would let her go ..she looks fine to me...but if it spreads on lower leaves or new growth then you should take actions

P.S thank you stitch
