Can thirst cause the leaves to look like this?

Different strains or all the same? I just finished three plants all the same strain and each plant

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 had the same experience this last run, leaves closest to the light were so stiff and then got crispy but with nothing that looked like nutrient burn. Far red packs a punch when humidity and temp aren't perfect I guess.

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.

For sure, I understand what your saying, but the leaves always look healthy when it's occurring. The plant I have now has leaves standing in the dark as well, so I don't believe it's a light thing. I could be wrong, but I haven't seen evidence supporting it being detrimental.

It was just one plant, as I turned the light up, the others followed suit. The initial plant that showed the signs was the only plant that wasn’t the same of 9 plants.

Ya, I've heard all kinds of things. I've heard it lack of Mg too, :lol:. The light theory just made the most sense. I don't think it's a problem though. I just think they do that especially on new growth when they're getting tons of light. It probably is gentler on the newer growth. I don't know. I don't think it's a problem at all though. I just think the plant is growing crazy fast and is trying to cope. The more light the more food they'll need too. Those bright green leaves on the OPs outer plants looks like the plants probably could use a little more something, maybe Mg. But if the light was less intense it wouldn't need as much.

So if the plant is growing healthy, and vigorously, I feel like it's a good thing. The plants growing fast and the leaves are pointed up, growing toward the light, but...... if you have anything off, temp, rh, nutes, ph, I believe that it'll cause problems. Not the leaves standing, but the light intensity. If the plant can't move nutes and grow, at the rate it wants to, because of light intensity, then deficiencies will most likely result. Just my opinion though. I have no science to back my opinion. Only observation.

Agreed 100%

The middle one is looking better today. I bet it was light intensity. Timing wise it makes sense. Someone mentioned they had one plant that reacted adversely when others didn't. I think it's prob just that. It took her a couple days to get used to the change in intensity. Today the left one looks like it's wilting and the right one def has something going I'm about to try to figure out after I post this. She's due for a flush, she'll get it tomorrow or the next day. The other 2 got theirs already but this one on the right drinks much more slowly. I would call that bronzing on the leaves mid plant. I'm following fox farm feeding schedule plus their powdered nutrients for flower. Plus fulvic and Si. It's my last run with fox farm. I have made a "living soil" that is now covered in mycelium! Here's some pics of everything.

It's hard to guess on that middle one. Didn't you say that one needed to be watered and was dry before, or is it always like that with the twisty leaves? When mine have done that it's been excess Ca and not enough Mg it seems like. And since you said the spring water is really hard I'm sure it's got plenty Ca and other stuff. You're not adding CalMag too are you? Maybe stop adding so much pH down too. I'm guessing you don't have a decent soil pH meter to check it?

Wow. Now the left one looks worse and the middle a little better, :lol:

I see those white spots on the leaves which I bet was too much light. Glad they're looking better.

No i do. I have a Bluelab pen. I have been using calmag and a lot of pH down. I don't know what the ph down is though. It's from GH but it doesn't say anything on the label.

I rarely use pH down. I've had the same bottle for a couple years. Lol

Usually after mixing nutes, my pH goes to 5.5. I dilute with ro water to lower ec, so that raises it a bit, then I use pH up to target.

The soil pH pen or the regular pen? I think the GH down is phosphoric acid but not sure. I'd stop using it anyways.

You've been using CalMag with the hard water. That's when I saw the twisting, but without the Calmag just lots of Ca in my fertilizer. I would stop the CalMag all together. If you have Epsom salt add some to you water or even add to the FF nutes. You've probably got way too much Ca and extra Mg could help. Just my thoughts. Or that pH is low from the pH down and FF nutes.
