Diary here.

It's early days and I don't want to panic or anything, but my environment is a little suspect (warmer temps than I would like).

I am seeing the same thing across three different tents. The seedlings are growing fast, but the shape is strange. I think I have seen this before, but I can't remember what the deal was.

I have done what I can to lower the temperature and raised the lights.

Anyone know what generally the issue might be?

Thanks in advance!

I grow in soil and outdoors so this is looking from a different perspective. When I start seedlings indoors my lights are old and run very hot which heat up my tent. I’ve had the same thing happen to me and different genetics express it differently and In my opinion it’s too hot and the plant is young and not hardened up yet. It can take a little bit for this to go away aka new leaf growth or if it stays hot it won’t go away and you could have a stunted plant that foxtails when flowering.

when my plants get heat stressed from the sun or if there is a heat wave coming through I make sure to get kelp in my beds. I’m not sure if there is any type of nutrient you can use to help mitigate the heat when running hydro. If you can’t get the room any cooler then try to get the roots cooled down by running cold water….. I don’t know how hydro works but I’m just trying to bring a outside view.

maybe someone will comment that know more about nutrients involved with hydro.

good luck!

Hey @matommy, your temps look good, 82f isn't bad at all, I hit 90f a month ago without my chiller too, so you should be fine there. It's the humidity at 46% that got my attention. If it were mine I'd have the humidity as high as I can, around 65%-70%. 

  The other thing is did you rinse the hydroton real well with PH'ed water?

  Are you using anything in your water as far as beneficial bacteria or hydrogen peroxide or bleach?

  Where is the water level and the amount of air (pump) is what came with the system?

  Your EC-.60 should be good for now don't mess with it yet. 

  Tap/water or?

@woodi2 Thanks for thinking about this!

The humidity is low because I unzipped the tent partway to control the temp, including the water temp. We got a cold front yesterday so I closed it back up this morning, but it only up to 46%. It will be 60 something soon, if history holds.

Hydroton was rinsed and Ph'd for a looong time. I have made that mistake before. Also, I am seeing the same thing on plants in soil in a different tent, but with similar conditions becauze they're both in the same basement.

Using Hydroguard as I have for a few years now.

Water is about 1" below the net pots. I am pumping 38l/min, per your recommendation from my last grow. It is about 40 gallons RDWC.

Tap water.

@matommy, Well Fine! lol So it sounds like environment, I use a small black humidifier connected to an Inkbird to control my humidity and it works well. Then I gave up on the water level below the net pot. When I place the seedling in the system I would raise the water level up on the net pot by a good 1/4" or so then I just left it and the plant couldn't care less. Then in flower they drink so much I'm just sloppy water in there and filling up enough to last till tomorrow so I'm filling to the max. I'm also in smaller net pot just so I can get more water under the net which means more room for roots, in my book. 

  So then what sort of air movement do you have? If your in a basement that should be fine, especially for seedling, but do you have good air movement everywhere in the tents? It just seems strange that it's happening to all the tents unless the humidity is that low across all of them, then maybe that sounds possible, I've never dealt with it that low, it would have been nice on my last harvest. But that's all I can't think of, if it's happening across other tents.

  Have you tried rinsing the above plants with Ph'd water and hydroguard through the hydroton? I do it weekly when their young, and check the roots to be sure their clean.

@woodi2 Thanks, I am chalking it up to how this strain must work (or not work?) since I see the same thing in three diff tents. But I also think you might be onto something with the humidity thing, so I am going to close the tents back up and whatever the exhaust fans can suck through the portholes will have to do to moderate temperature.

I'm hoping they slowly normalize. Each set of leaves seems just a little more normal than the last. I hope that continues.

Maybe I should check for leeches? I heard you're experienced with that.

This one is in a 2x2 cabinet 76f and 49%.

This is in the RDWC tent, showing the fans below and above. No shortage of air movement!

 This is the third tent. These were just moved from DWC to soil this week, so I understand if they're a little freaked. I am giving them to a friend as soon as she's ready.

these are all the same strain? Cause that Gelato looks fine, yeah pump up the RH in one tent, hydro tent, and put them all in there for 2-3 days, this will be a slow process, like check on them next week but pump them up and they should respond. Even putting some open water in the tent and warm air holds more moisture that cold air so higher temps won't hurt. I've got seedling sweating at 70% RH and 82F and their praying. lol You get it figured out. 👍

@woodi2 Numbers looking much better now. Thanks. I think they'll start looking like weed plants by the time I post a diary update Monday or so.

All the same strain, sprouted at the same time. I like your idea of putting some plain water in the tent. I'll do that. Thanks and I will post updates!

I completely missed this post lol, I have had this happen on one of my runs and it was just the strain expressing some strange things early on, once it got a few more nodes it started to grow normal, and it still produced quite well too. Love a good mutant.
