my plants are growing twisted (?)

Hi

This is my first grow, this are autos, they were looking healthy till some days ago they start growing to the sides, like i had LST them.

Sending photos by attachment.

Is this normal? Should i do something?

Thanks.

Uhhm , welcome to RIU

More information including light and where the light is.

Hi, thanks.

I have a 600W HPS at about 70/80cm (30inches) away from the plants.

The grow tent is a 120 x 120 x 195 cm x (4 x 4 x 6,5 feet). 150mm (6in) exaust fan 520 m³/h, 150mm intraction fan.

For the moment, the only oscillation fan i got is a 12 in and growtent is a bit windy inside. Could this be "wind burn" ?

The grow tent is also a bit too hot, with temperatures peaking 90º F sometimes (i need a cooltube)

anyone?

Sheesh, they be interesting, damn near horizontal before growing.

First thought is too strong a draught on the seedlings which has forced them over like that and at the stage you're at I don't think there's much you can do as they should have been supported to keep them upright a LOT earlier if that's the case as if you try to stake/support them to straighten them then the risk of snapping the stem clean off is rather high as I found out to my cost when trying to "straighten" one that wasn't nearly so far over as they are.

But snip off the lowest leaves, there's a risk of fungus if they get in contact with your soil, and you can TRY putting in a stake like a piece of bamboo on the "outside" of the plant to give it some support as it grows as otherwise the weight may get too high as the plant grows which could also snap things. Then hope for the best.

Thanks for reply. yeah, 2 of them have the root rolled up, kinda weird.

I planted them with taproot UP after germination, could this be the cause of the rolled root we see in the surface and the weird horizontal growth?

No idea, could be but even then had you acted sooner you would have been able to "train" the seedlings to go vertical.

Hopefully not a costly lesson, maybe put some more of your soil over the exposed bit of root, hope for the best.

Did you have you fan cranked up to try and offset the high temps?
Cover the root with dirt and stake the plant up straight with a chopstick.
No matter how high you crank that oscillating fan its still going to be 90 in there, you gotta get those temps under control.
You may be ok for veg but no way you can flower with temps getting to 90.

Oh and next time, just soak the seeds in water overnight and put them directly into the dirt.
They will grow just fine with minimal effort and less room for error.

I had experimented a couple of things to drop the temperature without spending extra money, and having the 12' fan a bit cranked up pointed right below the lamp would make the temperature go down some degrees.

I have decent intake air flow in the growroom, and the temperatures (where i live) should drop in Setember, so the problem should fix itself (hopefully).

I had germinated 8 seeds and only 4 sprouted... so yeah next time i will try directly into the soil.


For the moment i tried to straighten up the remaining 3 plants gently with some metal wire, like LST, not sure if this is hurts them, but it seem to help, they look straighter 2 days after.

Yeah I mean they will have a bend but gravity will take over and they will grow normally as long as nothing is pushing them over.
Its kind of like LST done with a fan instead haha.
Can you send a picture of your fan filter setup?.

anyone know what this is?

took some photos but they werent very good, ill take new ones later

i just saw it, might be due to PH fluctuations. I had been watering them with tap water which was 7.0 ph, but last week i bought some water from the store which had 6.3 ph and started to watering them with that.

If you're using good soil the ph of your water isn't an issue so long as it's not too extreme either way.

It’s to hot to much sweating of the leaves causes them to Nute burn lower those temps or use RO water I’m sure it’ll fix that problem

Too much light, heat and wind could cause this.

I suggest raising or dimming the lamp and directing the fan away from the plants. Preferably between the lamp and canopy. To help blow the radiant heat away and up to the exhaust vent.
