All branchs down, main stem up, 1 plant survived

[Terramoto]

First time i have this kind of problem and i dont know what it is, yesterday i went to see the plants and everything was OK. This morning when i went to see the plants like i do every day i found them like this:

Anyone knows what it is? the branches look like they lost all the strenght or the water inside of them, or like something is sucking them. The leaves look ok and i have one plant that isnt doing the same... Any hint??

 

[DaPurps]

Temps ? Did you feed them nutes ? They aren't dry ?

 

[Terramoto]

Nop, this happen from yesterday to today i didnt feed them anything... other then the branches getting down everything seems fine. even the leaves that are down look healty.

The temps are Ok, as you can see theres a plant on the right side that is healty

 

[Bebopp]

But they aren't dry? How do the roots look through your clear plastic containers? White and healthy?

 

[Terramoto]

yeah white and healty and they arent dry, 1 or 2 weeks ago i watered them with neem extract from THC , something like 1ml in 1.5L water and gave them half of that. Yesterday they were looking very healty this morning they were like this. 2 days ago i applied a twist on the branches and they were very strong, now they look thin like paper and they have a different smell, dunno how to describe the smell maybe something like sweet menta. They seem like someone suck them. think god i have the clones, but still one of the clones looks like its doing the same thing the others are all ok and one of the plants are ok too. What i did now was to trim some of those branches and drawn them in water to open air holes and remove anything in the soil that was harming the plants. someone told me to had a bit of water with soap in a tupperware because of the gnats and it worked, i wonder if the evaporation of that mix did this...

My thought is that the problem is in the soil

How wet do you keep them...had a couple of cindy99's do this to me...fed them a little to much and tried to flush them and I actually drowned the roots...

 

[Terramoto]

I water by the weight, when it is very light and also i can see from the glass plastic the soil. The thing is some of them were watered and others werent and they all got the same. Today when i went to check the plants i saw they were turning white, i guess they are dead. Normally the leaves would go first but in this case is the main stem/brances, this probably means roots started to fail or that the plant got instant death, which makes think that i probably killed them with neem oil (even if i gave them a week or two ago).

Did you add a new high powered fan that day? If not temps(I use the 24 hour humidity and temperature monitor from wall mart) or watering issues is there a chance a small animal got in there and knocked the stuff over? Just for shit and giggles I would check the perimeter for a small little hole.

 

[Grass Lands]

I've used neem before as a soil drench...at 1/2tsp per gallon with no issues...however the neem needs to be mixed thoroughly...

 

[Terramoto]

compost, Nop, the temps dont get higher then 23ºC i have a fan blowing air and the wall also makes the room fresh. dont believe so i live in an apartment and the branches look like they were sucked and not broken, they just lost strenght and mass.

Grass Lands, it was probably that cause i notice the top of the soil looked wet but when i touch it with my fingers it seem like it was covered with oil, probably the top water evaporate and the oil remain screwing my roots. But the funny thing is that i gave the neem like 1 and a half week ago, after that i watered the plants one time, wonder if being an oil if it can lock the roots from consuming the nutes or water...even so they are all white now and dead, looks rotten and the smell is different from any cannabis at all.

I was afraid of giving the neem oil....but i dont remember if i gave it to that surviver plant or if i didnt.

Hard to tell from the pics, but how much perlite did you add to your mix?

Maybe a drainage issue?

Do you have a cat or dog in the house?

 

[Terramoto]

In plain site, its a mix from composana. I've always used this setup/method and never gave me this problems, the only thing i see different is this time i applied neem oil and twisted the branches so they would get stronger.

RetroGrow, yes but they dont fit inside the that closet

They are all dead except the one that didnt show any signs of the problem, before they died the branch went white. which means every single cell died without getting dried, which means the root system wasnt the problem. Poisoning from neem seems to be the only thing that could cause this... Anyone has a pic of a overfeeding neem oil plant??

btw, i found a roach outside the closet but i dont think it was that...

Wow at first glance I thought you accidentally crushed them with the light reflector or something. It is curious that the furthest right plant in the photo is only half-damaged. the remaining back section looks A-OK. Fact that they all bend at the same height is interesting too.

Never heard of over-neeming though...

 

[RetroGrow]

Too much neem will do that. Been there, done that
Neem must be heavily diluted before putting on plants.
Pure neem oil will destroy plants, just like that.

 

[Terramoto]

BlueberryLovr, if your talking about the branches in front and behind those are two plants (the one that survived and the one that died)

the weirdest thing is (if it was because of the neem oil) it took almost 2 weeks to show any sign.
