Strange Leaf Curling

  • Strange Leaf Curling

    Posted by TheTrimReaper on November 30, 2025 at 8:33 am

    Does anybody know what this one blade on the leaves curling down may be caused by?

    My environment is in check temps around 78-80*F humidity at 60-63%. I put a new fan in there but its on low and oscillating, and this doesn’t seem to be totally consistent with where the fan is hitting the plant. It’s obviously not all over the plant but its got a few spots where this is happening.

    Look under leaf, i have had spiders do this. Pest such as mites. But i see no damage or danger. Watering, lighting. Sometimes the dli or resting of plants energy.

    I know this plant has to be hitting her DLI because it starts to droop about an hour before lights out. I don’t see anything under the leaves either. Maybe my watering got a little funky because I didn’t water quite as much this last round because it didn’t seem to dry out as much.

      @Thickems do you think that lowering the volume of water I gave her the last watering could cause this to happen? I’ve given a little too much to her before and seems to want to curl and look like an umbrella temporarily so I’m trying to avoid that- as well as the pots still had a little weight to them so I figured a little less volume wouldn’t hurt, but maybe just being consistent with it is better.

        Watering looks fine. Not seeing droop, yellowing, damage or fade going up.

      Looks like autoflower. I get this common on them too. I always feel its a vpd issue, i have played with lights, watering, enviroment. I have never narrowed it down yet. It seems to come and go in my situations.

        Yep it’s an auto and I don’t have as much experience with them. Seems to be a minor issue whatever it is but I’ll keep scouting for pests etc. maybe raising the VPD as she matures will help her grow out of it.

    Possible to much available nitrogen. A nitrogen toxicity can claw leaves. The tips, the claw, are you organic? These are things i come across too. Can wean out the nitrogen some, skip a feeding, cut the grow veg part back. Organic some amino acids carbon and micronutrients.

      Yep organic with top dressings. Worm castings. Been going about half strength on everything compared to what I normally do with photoperiods.

        Any easy way to wean out the nitrogen? I guess like you said just skipping a feeding, just going into the bloom nutes next feeding?

          Worm castings might be culprit, if added at wrong time. Thats what i would do, skip a feed and let the nutrient even out a little. The half doses i think are great idea in soil. I would focus on a bloom feeding schedule till finish. After the stretch and buds form this is when the plant doesnt require as much nitrogen. Focuses on that bloom nutrient needs.

            Okay, that’s what I’ll do. Minimal worm castings and only focus on the bloom side of things at this point. She’s not due for another top-dressing for about two weeks but I’ll probably push it back at least a week and keep it about half strength, I’ll be using Gaia green power bloom on this plant as my top dressing. Otherwise continuing as normal. Thanks for your input!

              You could top dress some bloom now. This is plenty ready for it. Then every 2 weeks a light dose. And microbes. They will love it if not already using them. I feel like you are doing everything right, just got the veg to bloom transition late. Not a big worry, you are going to finish perfectly fine on your path.
