Hello and help

[RastaFire]

Hello everyone,
New to this site and forums, trying to grow a few plants, I have some seedlings that are 17 days since they popped out of the soil. Using an apparently 1200 watt LED light on the veg setting. Plants seemed to be growing slowly on 23 hours on so I switched to 20/4 on, after that I noticed the cotelydons turning yellow/ brown, and then the fastest growing plant got a brown, dry spot on one leaf, not sure what would make them happier. They are jahbud× northern lights photos from seed in topsoil.
Maybe someone can help diagnose my plants issues from looking at the pics. It seems a bit cold in my grow room possibly, I am just watering with tap water. I put the lights back on 23/1 cause they seemed a bit happier that way. Not sure what I should try, please help..

Yikes.

Yep something went haywire.
First you should always fill the solo cup to the brim.
From the looks of it the soil could be either too rich or maybe anaerobic from no drainage an lack of aeration .

At 17 days they should be about 10x that size.

How much water
Type of soil

I am certain that's not 1200w. Most likely less than 300w.

Looks like probably a root issue.


For future I would pack solo cups with well aerated seedling soil with lots of knife slits all over the solo cup.
Have temp at 77 to 80 with humidity between 65 to 75%.

Hard to say what to do with these without a bit more info

They look hungry. Hard to say why without knowing feed schedule and medium. Also what ph you are feeding at. What nutrients are you using and at what strength?

 

[Reave]

Also try and take pictures in regular light so we can see. It’s hard to tell anything under a blurple.

Thanks for the advice, I haven't given any nutes yet just tap water a bit around in a circle every couple days, also haven't been monitoring ph yet either, dont want to spend alot of money on stuff tho the soil is moist not dry, they are in this soil.

 

[RastaFire]

Yeah the blurple does make it hard to see them I'll take some more pics, kinda regretting the blurple choice now. The leaves were green but some got splotches after changing the light to 20/4 instead of 23/1. Before the change only 1 had droopy leaves. It might have gotten too cold in there, not sure.

 

[Reave]

I do not believe that is a suitable medium for cannabis. You need something with drainage. Something simple like pro mix hp if you do not want to mix your own medium. Those plants are not getting the food they need from that too soil. It may also be “hot” for them.

 

[RastaFire]

Where's the best place to get that kind? Also could I just mix some perlite or coco with this kind of soil cause i have a few big bags of it. It doesn't say it has nutes in it so Im not sure it's just black earth with some small sticks and rocks in it lol

 

[Nunyabiz]

Another word for top soil with water added is called mud.
Its likely anaerobic, not much oxygen getting to the roots.

I would try to get some kind of seedling soil or at least a potting soil.
Need something with aeration.

 

[bluter]

soil is too heavy and the roots can't get air.
you can repot fast with 50 - 75% coco perlite mix, rest soil.

best is source cannabis soil, but i've done it with what you have on hand. only need about 25% of that soil in the mix.


edit: also you gotta feed them real nutes soon.

Yeah, next time get better soil. As for those seedlings, they are stunted permanently. It would take a miracle for them to snap out of it so don’t waste your time.

 

[NuttyProfessor]

as above too much heaviness to the soil , for those seedlings i would do equal amounts , coco, perlite, soil
the drainage at the bottom could be clogged up , make sure they drain good
as they are not autos they are savable

Black Earth Top Soil is a rich dark soil blend with CQA-Certified Compost. This soil blend will add nutrients and organic matter to existing native soils. It is ideal for general gardening use. Mix 1 part Black Earth Top Soil to 4 parts existing soil.

DIRECTIONS FOR USE: Mix 1 part Black Earth Top Soil to 3 parts existing soil.

so maybe hot and clumpy , i would do the three way dilute , coco perlite soil

seeds are costly so i wouldn't give up that easy , not too bad if you have money, if you do not work at them ,
never say die

I’ve saved worse. He could just put them in coco and start feeding right meow. Or coco and perlite and just ignore the soil. Bunch of options but all of them involve transplanting out of that thick stuff.

Hi Rasta You have some great people here helping. I can only think to firm up what you mentioned about the temperature. Under 64 degrees and they have a real hard time eating and growing. So what temperature are you seeing through lights out?

Perhaps I’m just speaking as someone with an abundance of seed, but what would be the point? The OP could start from scratch and end up with better plants than these in less time than trying to rehabilitate them. I guess if it’s rare genetics or the only seeds available, it’d be worth a shot, but otherwise more effort than it’s worth.
