anyone have any idea what this may b
Just gave first normal strength grow nute and micro. Thought maybe because the humidity is so low and temp fairly high.

Last 2 pics are of bigger cuts that are probably a month n half older than those early veg ones. I am thinking that is entirely dif issue. Also only a few of little ones are curling down on the leaf edge very little color change . And some edges are drying up that are curled down. Input plz …
Use ocean forest 60% coco 40% roughly(changing on next run for sure). Been letting it get fairly dry in between waters no real signs of wilt from dryness though. Using distilled adjusted to 6.6 And I didn’t get ppm last time unfortunately

Why distilled water? What are you feeding?
Things don’t look awful. Hungry and a little dry, but alright.
What’s your runoff pH?

Havent checked runoff yet. And distilled because I’ve been struggling w the public water. Great for drinking. But ph is way high running between 7.5 to 8.8 and ppm about 130. And even though I was adjusting to between 6.3-7 in the solution it seemed to climb back up in the soil. I did a soil test on a reveg krishna kush and ph was up between 7.5 to 8. So I’ve been more weary with these babies ( krishna kush x tardis) and trying to eliminate variables to figures out issues.

yea overall they look great but trying to figure out this curl issue before it gets out of hand. Will be transplanting asap also that should help I’m thinking

this is one in the front that was getting hit by fan the most is crispy dry and has some spotting on back portion of leaf .

Earth juice micro ,grow and catalyst are what i just used normal strength. 100 mil each I think then reg water . I Was using bigfoot in water root inoculum and put the bigfoot in soil mix when I transplanted(hf strength).

Does your humidity really swing between 12% and 95% in 24 hours? That seems drastic… Anything you can do to normalize that some?

pH always climbs if plants are eating. 130 ppm is fine, mine is 350+. You honestly want the water to have some alkalinity, that is, resistance to pH change.
They just look hungry from the photos. Maybe try switching back to tap, upping the feed, adjust the input pH to 6.

That would be from misting. Average is very low tho 20 to 30%

Il give tap a ago again and start delivering around six. Im Going to transplant tomorrow. Probably gonna go w Pro mix/topsoil and worm casting mix this timeand get rid of coco for now. I did not know that feeding plants raise ph. Only figured the organic ferts would help bring it down so thanks for the tip .Il keep ya posted on how everything goes.

The more I think about It could the curling of the edge and cupping have to do w temp fluctuations because the ones in the veg room are not doing this one bit and is a more constant temp around 70 75. Could it be that these fluctuations in temp and getting misted once or twice daily (going from 20% to 100% humidity) is affecting the transpiration and causing them to curl and cup?

Indeed. pH at root zone is a constant push/pull from several factors, but you’ll have an easier time with harder water. Extremely hard water has it’s own problems, but somewhat hard is better than too soft, in my experience. Less prone to swings. Like I was saying, my water is 350+ ppm if I pH to 6, it stays at 6.
Organics does complicate things a bit, but most fertilizers will lower water pH, especially phosphorous. As the plant absorbs those elements, pH rises. You have extremely soft water and hungry plants, this explains the pH rise.
Your temperatures and humidity are fine. I don’t think that’s the issue. I doubt your misting is the problem either.
Promix is fine, nothing wrong with coco either. Functionally they aren’t much different. It’s easier to fix problems in coco than it is topsoil, since it’s mostly inert. If I was in your shoes, I’d do just Promix cut with 1/3rd perlite, drop the castings, and switch to an easy hydroponic nutrient. Take the guesswork out of things. More time looking at plants, less time chasing problems.

Id switch to tap water and give them an epsom salt foliar

Switched to tap water last night and applied 6.0 adjusted nutes ( 300 ppm to big ones 200 ppm to younger).how much Epsom in 1 gal of water would u reccomend for foliar?
Like 1/4 teaspoon .

That cupping I see a lot when the humidity is low and the heat high like here now in winter, we have low humidity but my temps are around 80F as my extraction fan died 2 months ago, and I cant keep the heat down when ambient temps jump over night with the small fan I am using now temporarily.

You can bump up that feed quite a bit, I’d do double that.
Epsom foliar I do 1 tsp/gallon.

Yeah, it just got real dry and cold here and one or two of my plants started doing it. That’s my guess too.
