In all my years, never seen anything like this. The wrath of God?

[User420111]

Things were going well at first. Then the plants started yellowing out from base to top. I tried various amendments of nutrients like Cal-Mag and N-P-K. Tried lowering/increasing intensity of the lights. Nothing seemed to work. One day the sun leaves were vibrant and green, literally the next day they were emaciated and dried out. Not brown. Went from green to dead overnight. Entire sets of leaves.


I JUST watered the plants, that's why everything is so soaked.


Had to destroy everything. Mass casualty event. In doing so I discovered THESE! What in the holy hell are they and why did they decide to populate so fast? I think they're centipedes? I've never seen them do this. They are everywhere. In the pot bases, in the dirt, all over the grow tent. Like some plague was sent down from the heavens.

Any ideas?

I tried to grow some pot plants and instead I accidentally grew a colony of Sandkings

I'm going to go pray

Holy crap! I know that's no help. Had to say it. I'm super curious to know if those are larvae and what laid them.
If praying doesn't help, I know some great fire recipes.

[User420111]

Fire seems appropriate.

That's a bummer man. I put your pics in my insect id app and it identified them as greenhouse millipedes. Don't know how to post the link but you can Google it. Says in small numbers they only eat decaying wood but large numbers can destroy seedlings. Sounds like the nuclear option is best

[User420111]

Good grief. Says those things produce hydrogen cyanide, which can kill plants. No wonder the ladies weren't looking so hot. Yeah, sadly, I destroyed everything. Three weeks into flowering. Such a disappointment but reduces further waste of energy on a crop that will suck anyway. They didn't even smell correctly this time. Smelled like hay or some other grass. Not pleasant.

[Ckbrew]

That is bad. Burn it all and start over.

[DabberDog]

If you have hydrogen cyanide, you'll want to read up on flushing at the end of your grow.
Upside is you probably won't get aphids! Huzzah!

[Bowhunterwoody]

Shit man. Thats just wrong. Did you use a commercial soil?

[User420111]

No, I used my own mix. Which was probably the biggest mistake I could have made. It's nice soil, but not sterile.

Hey, User...
I have never, ever seen such! Sorry to see this.
Thanks to Orggrwr for ID'ing the culprit as greenhouse millipededes.

The key challenge is getting rid of them (and eggs) and sterilizing your tent before the next grow.

I would pitch any porous materials like fabric pots and soil and buy new, then spray/scrub down everything else with a 50/50 bleach/ water solution. Don't forget the tent exterior and underneath the bottom where it meets the floor. Reviewing your pics, I would disassemble your tent and wipe every inch clean.

[User420111]

Sadly, that is the best way to go. Going to mean a lot of work and probably nixes any chance of a Spring harvest, but oh well.

[Geeza]

Real bummer, man,
Sorry for you that this has happened, pests like this are the main reason I gave up growing in soil and switched to DWC,
Having said that, DWC can still have pests burrow into the root ball and lay larvae, but it just doesn't seem to happen to me as much as it did when I grew in soil.
Have a major clean-up and start again, good luck mate.

[User420111]

I may try something like that next time. Hydro exclusive. Soil has got so many potential issues.

[Ckbrew]

Coco/p hydro is the way to go...
