can someone please tell me what's wrong?

Many thanks
 
please can you tell me about your light and how much and how often you water??
and specifically what type of water?
I had the same issue and sorted it :D
:peace:
 
the stripes on the leaves is from ph swing, you like to try and make your ph perfect dont you.... I don't even ph any more cuz it was never an issue to start with.

the super curling is from an Manganese deficiency, are you using cal/mag cuz too much magnesium will block out manganese. you need to folair feed to get some immediate resuts
 
In my case I found that it was the chlorine as i used to use direct tap water which made the curls,
used rested boiled water nd they pulled off healthy.
:peace:

right i started with nute burn about a week ago so flushed with tap water ph 6.2. left for two days, this is the 3rd day of feeding them for ten minuites drip irigation. 140L resi, ph to 6.0, A n B canna coco 50ml and 20ml ata atazyme.

Im running 1x 600w powerplant bulb, temps right now are 77.1f and steady hunidity at 55 -58, still in veg for 3 weeks so temp rarely alters apart from when hot outside it can rise to 82f.
 
Yeah I also say that heat is the issue. What are your temps?

I had a heat issue a while back and my leaves looked identical to yours.

My ph is never below 5.8 and never above 6.2 as growing in coco. I am not using any cam/mag additives only using A n B canna coco nutes. I have got some dutchmaster A n B, I have never used this before as never had this problem before. Can that be used as folia feeding?

me too i use straight tap water, ph it let water get to room temp then feed for ten mins. ive had these fro about 3 weeks going all ok but just over night they look like this
 
temps aint high now, 77 should be fine, i run mine on 80-85,
and watering them too much also caused mine to curl and fade...
sonce i sorted them, she was fine. but the curls will remain, new growth should be healty and normal.
check on your nutes too, i dilute just 1 part with 10-15 parts water and feed them weekly or once in a while, and
if your leafs feel crispy or have a crispy texture its also due to dehydration from the feeding.
hope it helped.
:peace:

current temps are at 77.1 steady, light always on so stays that temp with hunidity around 55 - 58, only ever reaches 80= f when its hot outside

boiled water which has been rested and reduction of nutes worked fine.

secondly,
regarding this.

you will see yellow as well as curled leaves in mine in the bottom, i think thats what your were talking about,
its the nutes with leaf spots and yellowing,
that was also a result of nutes from excess nitrogen as the plants are still not resilient enough to handle it. so i cut the amount down and she pulled off fine...
told about her in my journal mate, here,

cheers :peace:
 
Dude I wouldn't stress about that yet as it might not be anything. Just monitor it, If it is a deficiency you will still catch it early and be able to correct it.

How many days have your leaves been curled like that for?
