Can thirst cause the leaves to look like this?

[ClaytonNewbilFontaine]

They're all drying at different rates and the middle one needs to be watered. I've never seen them curl up like this though.

What water and nutrients are you using? That middle one looks more like pH or lockout or something and not underwatering.

Are they in veg18/6 or are you flowering 12/12 ?

 

[cannabisweedPotNerd]

It's over water or under water

dim the lights and see how they respond. Might be too much light. Kinda hard to give you a solid answer with just pictures.

The water I use is from a local spring but it's pretty hard so I mix it with ro. Nutrients are fox farm.

2 weeks into 12/12

I actually just upped the lights the day before. They're at 75% now. I'm going to give that a try. Thanks

What's the pH of the water? I'm still thinking something in the water causing a little lockout or low pH. Just a guess though.

I dunno about that, but thirst will definitely make your skin look like the pic.

I think it’s too much light as well. I’ve seen my new grow stand straight up like the leaf is trying to rip itself off the plant. I lowered the dimmer & they went back to normal. The next day the new growth wasn’t stiff as a board.
This is something you can try without worrying about any ill effects before trying anything else.

I think you might be right about a little too much light, but the middle one with the twisted leaves is the lowest one and looks like it's in the lease intense spot. The ones on the sides I'd totally agree though. That super bright yellowish green new growth looks like it's getting tons of light. Have you seen twisting from too much light?

You mean like this?

Definitely not lol

edit: I gather your feeding appropriately in unison with the amount of light you’re hitting them with. If everything is in tune, I don’t think there would be a situation where too much light would cause any harm.

Yea with my current grow, but only on one plant. It’s weird. It’s a clone from a bagseed that turned out to be female, so I kept it. It doesn’t even like being fed. 1/2 tsp per gal of maxi bloom & the leaf edges claw from too much N. It’s a sensitive one for sure.
If I’m lacking on food, and the light is turned up the new growth will go contortionist on me. looking like an old green dead monkey paw.

 

[Hollatchaboy]

Definitely not lol

I thought you meant like that kind of leaf standing. Lol

More like 12 to 6 is what I meant. Lol
Check it out. It only happens on the new growth when the light is turned up past 20%. SP6500 is the light I’m using on them.

Mine have done that too before with the twisting. But it was excess Ca or something. What solved it for me was to add a little citric acid and some Epsom. So not sure if it's the Ca Mg ratio or what, but that has always worked for me.

To me that looks good. I feel like if the light is too intense, the leaves try to curl down and try to get away from the light, not try reaching up for it.

When they pray like that they're trying to get less light. Less of the surface area is exposed that way. At least that's what I've heard. But I see no problem with it.
