New to me- leaf curl

One or two funky leaves is nothing to worry about............if it was the entire plant showing those symptoms, then yes, you would have an issue.............but no plant will ever have 100% perfect leaves, 100% of the time.

From what I can see, the unusual blunt, twisted, and slightly curled new leaves on some branches are most likely caused by one or a combination of the following common issues: 🌱 Possible Causes 1. Environmental Stress (most likely) -Heat stress or low humidity can make new growth twist, curl, or appear "blunted". -Fans blowing directly on the plant can also cause wind burn, leading to misshapen leaves. -Sudden changes in temperature or light intensity (like moving plants closer to grow lights) often cause this kind of distortion. -Signs: Only newer leaves are affected, older leaves look healthy, and no discoloration is present. 2. pH Imbalance or Early Nutrient Issues -Incorrect soil pH can block nutrient uptake, causing distorted new growth even if nutrients are present. -Early calcium or boron deficiency can show up as twisted, odd-shaped new leaves. Check: -Soil pH should be around 6.2–6.8 in soil. -Water pH around 6.0–6.5. 3. Genetic Mutation or Reversion Sometimes a branch can show mutated growth (fused or odd leaves) due to random genetic quirks. This isn’t harmful and often corrects itself as the plant matures. 4. Pest or Viral Issues (less likely) Broad mites or russet mites can deform new growth, but you’d usually also see: -Shiny or blistered leaves -Very stunted, clawed tips Your photos don’t show strong signs of this, but it’s worth checking the underside of leaves with a magnifier just to be safe. ✅ What You Can Do Now Check pH of both your soil and your water/nutrient solution. Review your environment: -Day temp ~24–28 °C (75–82 °F) -Night temp not lower than 18 °C (65 °F) -RH 55–70% for veg -Ensure gentle airflow, not blowing directly on the plant. -Inspect with a magnifier (30x–60x) for any tiny mites on new growth. Wait a few days — if newer leaves start coming in normally, it was likely just stress and not disease. 📌 Important: Because the plant looks otherwise healthy and green with no spotting or necrosis, this does not look like a major disease or toxicity issue. It’s almost always environmental stress or pH-related when only new growth is affected like this. I hope that helps! 😘

I will suggest you not to fertilize anymore, don't water too much but put some bacillus or trichoderma in your water solution, check your lights distance and be patient. Girls look strong enough to recover, everything will be fine!
