Cannabis two week old seedling trouble, please help!

[mortaion]

Thanks alot The Hemp Godness and EllisD for your opinions! Really appreciated

I am still not entirly sure about the wheter its a burn or a deficiency or somethingelise but I think you are right it could be a burn.

Is there anyone experienced in this that can also confirm this or give their opinion, just to have a second one.

Really thanks for the recommendations, well I'll buy some different soil without any fertilizer, ill flush them and transplate them to soil which has no nutes (ill do my best finding one) and I will also add perlite.

1) How much perlite should I add?
2) Any other, recommendations?
3) Do you think that the plant will make? How big do you estimate the chances?
4) Will this have later an affect on the plant (yield,health)
5) If I flush and trasnplantate tomorrow, when will I see improvement? Will it still worsen for several days or will it directly stop and start curing?
6) On which key ingredients should I be looking for the soil?

Again many thanks and sorry for the questions but google is very controversial some say totally the opposite of others, but believe me I've done hours of research but it's extremely hard to see the difference in real life between a deficiency or burn for me.

Thanks!!!

I use a product called Kellogg's Patio Plus that I get at Home Depot. It is a good base soil, is inexpensive, already has perlite in it, and is organic. Check out the organic section for some good soil mixtures.

The nute burn diagnosis is not based on appearance alone, although the appearance is consistent with nute burn. Part of the diagnosis of nute burn is based on how hot your soil is and that you fed on top of that. The chances of it being a deficiency in a plant that young when it is in soil with that many nutrients in it is incredibly slim, virtually nil, IMO. Seedlings simply do not want or need any food until they are 2-3 weeks old. And even then, you start out with 1/8 or 1/4 strength nutes. Just to give you a comparision, the vegging nutes I use are 7-4-10

New growth on the plant is a good sign and they should most likely recover if you can get them in better soil. Any time you stress plants you affect the overall health of the plant and it will take some time to recover, but they should recover. The improvement will not be immediate, but they should not get any worse. Try and take enough of the old dirt so that you do as little root damage as possible. But you also do not want any more of that soil than you absolutely need. Your tomatoes may just love it.

Keep in mind that while people may say that cannabis and tomatoes have the same needs, they do not. Cannabis has its own special needs and there are fertilizers formulated for the needs of mj.

Take a look at your Cotyledons. They look green and healthy, yeah? They have all the nutes in them that your plants needs. Until they start yellowing, you really shouldn't even have to consider nutrients. Also, with no airation the roots can't breath or drain properly.

So it looks like nute burn from hot soil with new seedlings and you could use different growing medium. I'd highly consider what I recommended and wish you lots of luck :aok:

Ingregients:

Peat Moss, Coir, Perlite, a Multi-species Blend of Endomycorrhizae

Applications:

Designed specifically for growing indoor foliage crops, vegetables, herbs and other consumable crops.

1) How much perlite should I add?
A) I didn't add any, my soil had it.
2) Any other, recommendations?
A) Make sure your fan is giving enough air movement around the space and that heat isn't an issue. Not really fully a recommendation to your diagnosis, just a general thought I've had.
3) Do you think that the plant will make? How big do you estimate the chances?
A) Yeah, I do think they will with new soil and proper lovin'.. but I'd say you have a 75/25 chance, 75% being good. Don't over water and don't let it get dry (watch it good with your new soil, it will drain way better than this stuff!)
4) Will this have later an affect on the plant (yield,health)
A) If you catch it soon enough it shouldn't, but if it does, it shouldn't be detrimental at this point.. it hasn't had a chance to take off. Are the seeds "autos" or "photos"? That's a determining factor to if you've stunted the yield as well
5) If I flush and trasnplantate tomorrow, when will I see improvement? Will it still worsen for several days or will it directly stop and start curing?
A) No matter what, expect those leaves to dry up and fall off.. LET them though. The plant will let you know when the leaf is weak and will either fall off on it's own or you'll "graze" it off. I think you would see improvement within a solid weeks time, gradually over days. It may look worse after it looks better though, if you're putting into new soil, so be prepared for that mentally lol.
6) On which key ingredients should I be looking for the soil?
A) Perlite, Coco Coir, Pete Moss


Remember I'm new, but other members will gladly step in and mention if I've said something wrong or at least elaborate. Be strong, and don't worry too much.. you can always plop some more seeds at this stage.. at least you're not at week 4-6 with detrimental issues :aok:

 

[Hushpuppy]

I was going to come back and explain this for you but my "Grow Friends" have explained it better than I could have, and they also saw the need of using different soil as that soil (which would be great for tomatoes) is too hot and too dense for MJ. I think some good organic soil would be ideal for you as it usually has a good mixture of nutrients and aeration that the seedlings need.

The sooner you can get them moved out of that soil and out of the high level of nutrients in that soil the better your chances of them surviving.

 

[mortaion]

Wow you all three have just made my day (and saved three cannabis plants), really.
Unbelieveable how gentle and nice you guys are, very patient, very mature and giving very good information.

Really so satisfied I made a topic on this forum, best forum ever!
Over a week I'll be back with new pictures and information to give you guy's some feedback, let you all know if it worked out or didn't.

Thanks!

 

[The Hemp Goddess]

Oh, don't make us wait a week. Let us know how it is going.

Thanks for the kind words. There is something that is just so special about growing your own. We are quite happy when we can help someone else learn to grow their own and be independent.

 

[Dr. Green Fang]

Yeah, this place recently helped me out (few months ago) and I only find it proper to pay it forward in some other threads.. cheers for listening and starting the topic. :aok:

 

[trillions of atoms]

You have a strong soil and no drainage due to composition of soil......

transplant and add perlite , worm castings and dolomite lime...and water well after the plants dry good.

problem solved.

 

[mortaion]

As soil there is just no nonfertilized soil in my garden center, unbelievable.
Ill think I'll just buy some bricks of coco peat add perlite and 10% of my current soil which will be flushed first, should this be allright?

 

[Dr. Green Fang]

there is just no nonfertilized soil in my garden center, unbelievable.

Do a search for Hydro stores in your area. I have to drive 1 hour and 20 minutes one way, just to get to my store.. but it is SO worth it!! :aok:

 

[mortaion]

Went to another gardenshop and also there, they didn't had soil that didn't contain no fertilizers so they recommended me the one with the least ferts, 7-6-6 NPK , organic enriched with Mg and Ca it sais. Based on coco peat.

It looked quite decent, I also bought a bag of perlite (1kg, 10l) I will search google for a good ratio to mix, flush my plants right now and then transplant them into their new soil.

What you guys think?

 

[The Hemp Goddess]

You don't have a Home Depot or Lowes or hydro or grow store? There are many companies that make unnuted soil. IMO, 7-6-6 is still pretty hot. My vegging nutes are 7-4-10. and they don't get fed full strength until they are about 4 weeks old. In addition, YOU want to be the one to contgrol the nutes, not the soil. 7-6-6 may be fine for tomatoes, but it isn't what cannabis wants.

Look up some good soil mixtures on line. Mandala cautions against using too much perlite in your soil mixtures. In addition it is a non renewable resourse, so I try and not use too much.

 

[Grower13]

I've read you can mix 100% organic peat.... perlite..... vermiculite..... together. 3parts peat, 2 parts perlite, 1part vermiculite....... I was gonna use this until I found promix in my area....... still had to add more perlite and vermiculite to my pro mix to put more air in the soil. MJ likes to get wet and dry out often to grow its best in my experiences with it.

 

[The Hemp Goddess]

I think that peat is too acidic to use in that strength. And perlite and vermiculite do about the same thing, which is help aerate the soil. I'm thinking that the soil mixture is going to need to contain more.

If the place he lives has a couple of garden stores, I would think he can find some kind of soil that is not nuted somewhere.

 

[mortaion]

What I've done right now:
Flooshed the three plants while being in their original (bad soil) container with 3.5times the volume.
Next I've made a circle of about 3.5" in diameter around the plant, digged it out and repotted them in the new soil* a 2liter pot (3/5gallon +-).
*The new soil, which sourrounds the plant, under , above and on the sides is made from a commercial coco peat soil that I have combined with perlite. I've used approx 30% perlite and 70% peat , I guess..
After that I flooshed (2x) the new container yet again to get rid of some the NPK rating 7-6-6 which is in the coco peat soil. Since the perlite is pure and doesn't contain any fertilizer I think I will be fine, I really couldn't find anything lower then NPK 7-6-6.
When the mixture was moist I could see a big difference with that soil being moist and the soil beforehand I had being moist. This soil drains aloootttt better, feels better, feels airy, I think it's okay?

Pictures will follow. Any other comments or advice? Would love to hear/learn.

(P.S: You all were right, it was a nute burn not a defficiency I've did some research and compared photo's)

 

[mortaion]

Here are some very detailed pictures, I think.
How is it looking? Do you think it will make it? Wat should I expect the coming days?

 

[trillions of atoms]

the new growth looks good, dont worry about the older leaves.

let the soil dry out really good before watering again. sprinkle a lil dolomite lime on top if you didnt add it to the soil.

you will see them come back around. NO NUTES!

 

[mortaion]

Great, so happy
In the coming days, will the leaves still continue to somewhat get more yellower or brownish or will that stop immediately?

And will the NPK 7-6-6 harm? although it's partly flushed away (I hope, not sure)

 

[Grower13]

Please let me know how the soil does for you....... hard to get the right stuff in my part of the world too......... I think your plants are gonna be fine now........ good luck
