Leave edges curling

[Revon08]

Can someone help me identify this problem and how to fix it please. Thanks a million.

What is your rh like? Looks like heat stress

 

[Revon08]

Thanks for the response. I’m first time growing. Light I’m using is Phantom DE and about 3-4ft above. And it’s in 7galon pot coco

 

[SirSmksAlot]

Do you know what the humidity level in your space is?

 

[SirSmksAlot]

I was having the same problem. My humidity was under 20% and I 5hink my light was a bit to close. Im running 2 humidifiers and moved my light a bit and it has fixed my problem. I try to keep my room above 30% humidity

 

[Revon08]

Humidity around 38 - 44%

 

[SirSmksAlot]

Hmm. How close is your light?

 

[SirSmksAlot]

Never mind I see it's 2 or 3 feet above. How about fans?

 

[Revon08]

About 3 - 4ft above the plant

 

[Revon08]

Yes and oscilating fan running 24/7

Photo or auto?
What light schedule are you running?
What are your temps?
Is it on the entire plant?
Do you have a full plant pic?

Go to the menu on this site and click on plant problems and type in leaf edges curling. It looks like it could be heat stress, root problems or over or under watering

 

[Mr.furley]

Check your plants for broad mites

 

[Revon08]

It’s from the new Photo seedling.
Temp 26c
light 18hrs
New and medium grown leaves are curling. Not old fan leaves.

It's sure is looking like heat stress (but at 26c), at what height do you take your temp reading?
Back off the light distance or dial it down 1/3, if thats's an option.
I would go to a 16/8 on/off schedule until resolved, regardless of the cause.
If it was roots- the whole plant would do it.

 

[Revon08]

Temp reading low 19. high27. And lights just dialed down to 825w. See if it help. Gonna check roots later

 

[Revon08]

Roots look great

It looks to me like there is still too much light. Can you turn it down more?
The plants look like mine did when they got too close to light or were in hot spots.
Do you have a light meter app for your phone? Some are free and work well.

Your leaves are tocoing or trying to protect itself from to much light and or heat or both imo

I would agree with Weed Pharma, The lower leaves and branches are taking all the water and the topside is drying out because its using more than it can take in. If you touch the leaves and they are dry and a little brittle it's usually from heat stress from lights high temps or under watering. Spray the tops with a light mist if no buds growing and the lights adjusted. Rehydrate the leaves.
