WTF is wrong with my plants?

[troutman]

one last suggestion , the surfire way to know if its pathogenic or genetic is to pop parental seeds. if they react the same way you are doing something wrong with the setup, or it's a pathogen; on the other hand if they are fine, your problem is inherited weakness.

I guess my only option is to try more seeds and hope things get better next time.

I think it's a soil pathogen and will do what I saw 1 person do in a video. The person
uses hydrogen peroxide as a soil drench to sterilize the soil a few days before planting.
I think soil parasites like to find soil bags and those kept outside in garden centers are worse.

The soil I'm using came from my local grow store and there's also a slight possible
chance that another person growing Cannabis tracked in soil parasites into the store.

I would be willing to bet that's how some growers get spider mites, etc. Like a grower
with Spider mites rushes to their grow store to get an insecticide not knowing there's
some Spider mites on the clothing.

Guess, it's time to consider anything new as contaminated
from now on and sterilize and/or wash anything that goes
into our gardens.

Guess, I got some major cleaning to do.

If you say you got your soil outside of the store, I'm thinking fungus might be the likely culprit. Spores in the wind, man... But yes, sounds like a peroxide drench (and possibly a run in the oven to sterilize things through and through?) might be your way to go.

That's a lot of work. I'd just source soil from a different store. Save that soil for your outdoor gardening next spring

Sucks, but I culled everything but the Catnip. It's for my sister's cat and I told her to come get it.
I'll make sure to only give her the tops and not the soil or pot. Even though she has no plants I
don't want to risk spreading a plague. It will be gone well before I start any other seeds or even
get new soil. I'll start cleaning the tent tomorrow with dilute bleach spray and wait a few days
after before getting new grow supplies

The store I was going to is closing at the end of this month. So yeah, a new store it is.
I always save used soil in my shed over the Winter for outdoor growing the next year.

When I start again, I'll go the safe route with a 50/50 mixture of perlite and vermiculite
in solo cups. This will rule out soil pests in a hurry. Once the seedlings take off they'll be
more resilient to any problems of soil growing. By then, I'll have ordered at least one
beneficial organism to deal with soil pests.

Sorry to hear you’re struggling man. Been there for sure. Do you ph your water? If so is your pen calibrated? I always start with the simple stuff before assuming the worst like some pathogen. Hope you get it straightened out brother!

Most bagged soils sitting outside get all sorts of stuff.

But, no need to use peroxide, or to even go the extreme route of perlite/vermiculite.
Like you said, you've been growing in that soil without peroxide for decades and no problems.

Also, the other plants are healthy, so its not viral and very likely not a pervasive fungal issue.

Looks to be either metabolism is low (low temps) and did they start off under LED?
I had a similar issue growing in the Fall/Winter under LED.
Or, its genetic.

Your best action for now is no action, other than ensuring the soil is warm enough.
Containers on cement floor in Fall/Winter is a big culprit to many problems.

I agree on soil kept outdoors being a possible source of problems.
If it was low temps or fungal issues the 4 bigger test plants would
have suffered as well. I control the basement below me and set
the heat to 25°C so my floor stays warm.

Luckily, I have lots of seeds and can start again.
So I will start again after I clean up cause using
sick plants for breeding is a no no. That soil is
all outside in the shed now.

Could you answer the question that your problems started after 25 years of successful growing after you switched lighting to Led? It might be an important factor.

I've been using these 2 LED's for the past 2 or 3 years at least. I even have a light meter
to make sure I don't raise the light intensity too fast with the built-in dimmer switches.
The previous crops before I ran into problems these past few months went off without
any such problems.

i reckon that funky growth looks like soil pathogens gnawing on the roots or root rot.

Did you get a chance to look at the soil/roots under a scope?

I did look at the soil using a USB scope and noticed Springtails and some type of Nematode/Worm.
The roots looked chewed, stubby ends and didn't go far. So I'm 99.99% sure it's something in the soil.
Springtails they say are harmless under normal conditions. But they will chew dying roots also from
what I read.

I'm getting 100 of these to deal with pests once I get my next grow started.
They breed fast and are easy to raise using pet food if there's no prey around.

Targeted pests​

• Fungus gnats
• Moth eggs
• Pest nematodes
• Root mealybugs
• Root Aphids
• Shore flies
• Springtails
• Thrips

Dalotia coriaria - Anatis Bioprotection

The beneficial insect Dalotia coriaria feeds on small invertebrates on the ground (shore flies, fungus gnat, midge, collembola, root mealybug, aphid and mite pest), vegetable greenhouse crops, mushrooms, potted plants and nursery.

A little diatomaceous earth mixed into the top inch of compost may help eliminate the critters.

It's one of the little things growing with leds you have to get around as the compost stays wet and colder for longer which makes compost bugs more likely.

With hps, due to the extra heat, i find the pots have a better and shorter wet/dry cycle of 2 or 3 days which discourages these soil bugs.

Oh man that sucks big time...
Had no idea you were in Ontario, I know a friend there (but in the south) who was also involved in cannabis very much.
I've seen my little clones do the same thing...

Then I found what I believe were winged root aphids (there's a thread here in IC) and their larvae munching on the roots, plants looked exactly like yours. THICK layer of perlite topped with DE in fabric pots killed them as they need to come out of the soil at some point and then the DE cuts them up good. Just water carfully from the bottom as otherwise the DE will turn into sludge and not work anymore (other than adding silica to your soil)
Do you have any fliers looking like fungus gnats? If yes, I'd look into this potential scenario...

All the best of luck man

If you get one of these handy things and you have those critters, when you suck up excess water after watering you can invert it and then hold it up to the light and see the tiny larvae zig zaggin around.

A Neem watering + perlite top has always got rid of them for me.

Hey Troutman not to derail this thread, I'm from northern Michigan if I were to go into Ontario where would I find the biggest brookies? 20+ inches preferably lake fishing...the brookies grow to world class size up there....sorry everybody I had to ask lol

• Nipigon System. On July 21, 1915, the world record brook trout was caught in the Nipigon River. ...
• Lake Superior. ...
• The Winisk River. ...
• Algonquin Park. ...
• Wawa/Lake Superior Provincial Park. ...
• Sutton River. ...
• Thunder Bay district. ...

I'm in Sudbury and have caught many Brook Trout up to 4 pounds and lost a few almost twice that
size. Fish over 8 pounds are normally only caught in remote lakes. Some lakes are open all year and
it's fun fishing them at 1st ice in 3 to 5 feet of water under 3 to 4 inches of ice when the lakes just
freeze over. Most people have never experienced ice fishing under those conditions for trout. As
long as you test the ice 1st and don't dare go far onto the ice it's ok. I did fall thru once, but it was only
3 feet deep. lol

The action can be mental and one time while doing the same on a Rainbow Trout lake
when it 1st froze in December my brother and I had 2 holes each and all the sticks went
down at the same time. He got his 2 fish and I got 1 while losing the other.

Fish up to 8 pounds are caught in many lakes from Sault St. Mary
to Sudbury and going North to the area Gogama.
