Hello im on my second grow and am about 2 weeks into veg from when i picked up the clones. Ive been in a 5x5 tent but jsut upgraded to a 10x5. I had to take down the 5x5 before i could set up the 10x5 so i had to take my girls and put them in the bathroom for an hour while i set up the tent solo. When i came back to my plants my two Ace of Spades and my Berry Skunk were drooping really badly. The entire top of the ace of spades were drooping over and the bottom half of the berry skunk was drooping really bad. Why??? Im freaking out and have no idea why, but it happened in the hour in the bathroom. If someone knows why this happened and if the plants are going to recover i would love to hear your thoughts. Thanks here is some pics

Side note: Not sure if this has any effect but i fimmed all of my plants a couple days ago. Could the stress from that added to the change in environment cause the drooping?

Looks like rh shock. What was the rh in the respective spaces when this happened. Don't freak out. Almost never a good response unless leo is at the door. Try getting the plants in rh of 40% or more. Mist the tops. Wait.

Patience is very important in this hobby and in life.

Cold floor in bathroom could have shocked the root system if placed on floor. Almost looks like mine after I watered a day late were they real dry ?

Fimming didn't do this. For some reason the plant wasn't/isn't getting enough water through its root system from the soil.

original grow rh was 35% and when i put them in the bathroom which is a pretty small space, the entire floor was filled with pots. I turned the heater on to keep them warm. I think humidity shock is a good possibility because it was pretty stuffy and hot in there, i closed the door so my dog couldnt eat them and it probably trapped a bunch of heat. My new tent is 78 degrees and rh is 32%. I dont really have a way to increase rh.. do you have any methods? ive heard water in buckets can do it?

I have a couple methods. first one, regular humidifier. it did a decent job except when venting the room. Second, I used a 'y' fitting on a 5 gal pail. Then i hooked up a 600gph pump to sprayers in the bucket. I created a 't' with 1/2' od line and put 2 sprayers on either side. Every time the fans vent the pump is powered (off a t-stat controller) and the sprayers create moisture that is pushed into the room by the fresh air intake.

I had air intake rh of 15% and lower. This solved the problem of intaking 15%rh air into a room with 60-80%rh. In other words, this solved the problem of massive rh oscillations in the room. It's simple and effective. I was even running a bare bulb. There is some finesse to this tek. You have to put the sprayers facing down and use gravity to your advantage. If you don't do this properly you could have h2o fly through the air and hit the bulb. I understand that could be very bad. You are forewarned.

I tried the 5 gallon pail with h2o and it did not solve the problem. Sorry this explanation sucks. No i don't have pics. Not a big fan of pics. I wish i could explain this better for you. I was actually planning on doing a thread for this later on cause i figure i'm not the only guy to face this problem. This issue of incoming air rh can also be solved by a furnace humidifier mod to your air intake. That, however, costs $200. I had stuff lying around so my only cost was a $60 pump.

I hope this helps.

As a note: you will hear stuff on forums about optimal rh values. I don't believe a lot of it. Here's why: unless you have a landrace/genetics in a varietal from a landrace which is adapted to low rh everything i have ever seen tells me that this plant grows best at 50%-85% rh. Sounds high right? I have seen fantastic growth in this range (vpd tables back this up). Also, i have seen drywall get black mold/white mold/pink algae and the plants 6 feet away are booming. I don't recommend this rh level for the second half of bloom. At that point i would want to be down at 50%.

I don't think that the powdery mildew, bortrytis, etc growers see is always rh related. I think the plants are not optimized and that their defenses are compromised. There are so many species of molds and mildews and they are 'landraces', ie. they are specific to a given ecosystem. This is why i think it is so tough to know exactly how far a guy can push it in the upper range. Also, at the lower range of rh the stomata begin to close AND every chart i have ever seen tells me a lot o plant pathogens thrive in low rh. I would rather fight high rh than low.

Sorry to ramble but this is a complex issue and hard and fast rules don't exist imho. There are just too many variables at play.

Finally, I will say this. I believe it is very important to filter the air intake. I use a good quality furnace filter. Not just to keep out spores but larvae as well.

I really hope this helps. I am convinced that your plants got rh shocked somehow. I've seen it before. Yours look exactly like a cut in rockwool that is bone dry. iow, the moment i saw it i thought 'wilted'. Don't worry, this is a great learning opportunity.

I apologize for my long windedness but i am very passionate about plants and rh as i bought a lot of dogma and it caused me a lot of problems.

Success.

Ive got a small dehumidifier I got from walmart but it runs out of water every 12 hours, which is a bitch. Are you saying if i bump my rh up in my tent i can reduce the stress on the plants ive caused? Also why did it just happen to 3 of my plants when there was 15 or so in the room and the others werent effected?

root mass, varietals, how close the heater was.......
tough to say
Yeah the humidifier thing is a bitch; when you can afford it get another one. Hey we all do the best we can with what we have and our budgets. Nothing wrong with that.

what i always do is take em to the bathroom, mist them, maybe even water if they need it. I never worry about cold if it's too cold sure but 20c ain't gonna shock a plant
years ago guys were saying that if you watered with cold water right out of the tap the plant would be shocked. not true
there is still a lot of misinformation out there. the problem is a lot of guys have never grown anything. i guess they feel that they need a lot of 'rules' because they know so little. people say a lot of stuff that isn't true. I've done things that people say can't be done. All as part of my learning process. 75% of what people say about cloning or seedlings is frequently false. Guys say peat pucks suck. They work great for some varietals but not others. I doon't know why. Rockwool should weigh 5x it's dry weight. Anymore and it's too wet and success won't occur. Even still, some seeds don't do well in rockwool. I'm still trying to figure that one out. LOL

Here's one for you: at a certain point in cloning if i don't see roots i stop watering the rockwool. people will tell you this doesn't work. I let the cube dry up. Almost completely. The plant is now forced to put out roots or die. they almost always do it. Do it recommend this to everyone. no. it's a strategy i learned by observation.
Another one. you can't feed seedlings or clones at the same nutrient levels as a full grown plant. you can. A seedling with 1 true set of leaves is ready for 1000 ppm. A clone with roots? the same. But, other factors must be present: 1000 watts at 36'', good temps and rh, etc.

That's why i referred you to those sources. If you will read them, you will start to 'see' what is happening in front of your eyes and know what to do because you understand. I'm not knocking other people per se. What i am doing is trying to encourage you and anyone else to learn enough that you can then teach yourself. I've read thousands of pages over the years. I'm not saying you have to do that now. Just be committed to learning and be skeptical in a healthy way.

I'm not a prick but i am firm on certain things. I leave debunking up to other guys. I try to help guys out so that they can be successful and i do it selectively.
Part of what i try to impart to people is to be scientific. If you walked into riu and randomly read you could easily form the idea that this plant is unique (it's not-grows just like tomatoes in many ways) and that you should immediately start attacking the plant and ripping fan leafs off (bad idea).

Sorry dude. I am a pretty funny guy. I didn't mean to be so intense. I guess i"m trying to help people because my own learning process was long and painful: had bad info, got duped by morons at hydro stores, you name it I've been there.

Good luckl

btw looks like your in the zone. they should bounce back very quickly.

Just so you know fimming is very unreliable. i read up on it. I wouldn't do it because i don't believe it works consistently and many varietals don't like it (think cactus style growth pattern-these should be left alone to grow as single cola plants becasue they are programmed to). Bush style/ xmas tree growth plants can take a lot of manipulation and keep on trucking (seen it first hand). I will at some point "prove" the cactus thing to myself with expendable plants.

Also, i hope to post a 'how-to' on my rh intake tek at some point. I'm sure it would help you and a lot of other guys (it sure helped me;) ). Without pics only a small % of guys will figure it out because it is a bit tricky.

Good luck dude.

Sorry, I have to call BS on a one hour change in humidity causing this. I'd look to where you had your heater positioned as the culprit.

Ok so its been a couple days since this started and they still havent recovered. IS this nute burn along with everything else? The entire top of the plant looks dead to me. Dried crispy leaves like this. Some are worste. Ive never seen black dots like that before either. Anyone know?

The heater is a floorboard electric heater that was ground level with the plants which are in short 1 gal pots. But they were right in the middle of the room, not the closest plants to the heater. There were maybe 2-3 plants that were closer to the heater that growing good. I have seen noticeably slower new growth since the move. Whatever i did i definitely stressed them.

Is there any hope for the ace of spades are should i find replacements for them?

I can't see rh causing your problem either. I've only seen changes in rh affect very young transplants or clones. Basically undeveloped plants. Taking clones out of a dome with 90% rf and transplanting them in a room with 30% rh without getting them used to it will do it. Even then, they bounce back in a few hours, maybe a day and they are all right. You've got something else going on here.

No that's not nute burn. Nute burn starts at the tips/edges of your leaves.

As for the drooping plants, I'm stumped. Did they perk back up when you stuck them under your light again, or did they stay that way?

No they are still drooping over exactly the same. It looks like the part that is drooping is dead. The stem is soft and flimsy.. Any ill effects besides shock on just chopping off "dead" section?

I just cut off the top of the ace of spades which is now a white/dead stem with dead leaves and the inside of the main stem was bone dry. There was actually a black hole in the middle of the main chute.. That cant be good, can it? haha

Maybe there is another culprit as others have indicated. If it were me i would cut below the damaged area and hope for the best. Sorry that did not occur to me earlier. I should have said that if things don't bounce back in 24 hrs. that 'topping' is the next option. my bad. i still believe that the wilting is rh shock perhaps brought on by a heater creating very low rh. just my vho.

good luck
