There has been clawing on this plant for a long time, too much nutrients when it was young. (First time grower on my first plant, my others are fine) it’s also the largest plant in the tent intended to head outside soon. The clawing overnight has radically increased after a watering two days ago, and the leaves are now canoeing down badly.
Temps are 70-80
Humidity 50-55%
pH 6.5

What PPM's are you feeding? Too much Nitrogen.

What PPM's are you feeding? Too much Nitrogen.

im not feeding anything besides rainwater. When it was younger I used too much liquid seaweed and I haven’t given and nutes in 2 months. ppm is usually 3-5, when I use tap it’s about 60-70

Looks like water stress to me.

Sounds like the soil is still hot. What light are you using and how high?

It’s a king LED 1200w and it’s at least 3 feet above, I also don’t have both light switches on anymore, just the blue veg light. I did add compost tea a long time ago and the added nitrogen from the seaweed I think is what’s causing the excess.

You probably need more light. I would at least have both sides on.

I thought I was getting light stress on the top, they were curling up on top

I used to have a very similar light that I tried once. I got rid of the pos and went back to HPS. They are cheaper and work ten times better. That light is really only 200w with both sides on + another 40w for fans. A 250w hps will outperform.

teepee temp? bout 250 burnin watts, yes? 3' plenty
but temp n rh ... i c N
as well
no diox
right?
3-5 u mentioned ppm not ec
assuming 3-500... ppm?
just verifying stuffs

fellas

quicky solution occurs

as opposed to tweak

wait n c

what about simply resetting medium/flushing

that n out

instead of dicking around n wait n c?

would help metabolize some of the surplus

can have heat damage without bleaching

surely

but i know kings

and even 79 sees this

ignore the 1200 it ain't hps

and king par from afar sux

and they could do better

with heat dissipation

leaf surface temp

look into it

rh is important in combination

that looks like waxy N toxicity to me

heat claws just as bad

 

[SPARECHANGE]

when lights go on

can we get more pics

high

low facing

angular

and from above canopy?

airflow?

inline?

fanz?

someone said watering shrug

too

we lettin em dry out

temps n humidity

just noted

yummy

leaf surface?

at 3' with that light

those other figs u gave

N...

watering... 2 days ago

prolly not overwatering at 2 day pics...

medium? good drainage, or retaining?

Over watering with the leaves recurving as they are how’s your drainage do you have your pots up off the tent floor with air gap under them ? Od

They are directly on the Tent floor in fabric pots. No air gap.

here’s how I set mine up hope the pic helps warmer dryer roots aids in plant health , if using drip trays get pot risers under them never let plants sit in run off .

Hey mate I had this problem too and believed it to be from overwatering, combined with bad VPD, cheers!

VPD?

VPD?

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

i notice the duck feat on the plant on the right. what's its its history? clone? forced? taken late, etc? looks very pretty, structurally. strain?
sorry to jack thread. i HAVE to know!
