Hey I’m new to growing and also to this blog, I having weird leaf tip curling/mutation on my GSC auto in week 3-4. I’m growing in Mother Earth coco/perlite 3g fabric pots. I’m using growth science A&B plus solid start. I’m watering at e.c 1.05 ppm 500 ph 5.9/6.0 till 20 percent or more of run off. Run off is ec 1.6 ppm 750 pretty consistently. Im using a Famurs tf1200 110 watts from the wall full spectrum led. Im 20” from tops at 100 percent power. Room temp is 78f day and about 77/76 at night. Exhaust fan, 6” fan blowing and humidifier. Grow space is 2 by 2.5 feet. Also I only use spring water starting ppm 17-20. Pictures are day 25 Will include photos, thanks I appreciate the help and advice

Agree with Reed71, don’t see a serious issue.
Leaf edges curling upward are typically from conditions that dry the leaf faster than it can replace the water. So too much light or heat or wind may do it. But yours are barely showing that problem. If the fan is blowing directly on them you might direct it to blow over the tops or beneath the plants. It will still move air enough but will slow the loss of water from the leaves. Plant node spacing is tight. That means the light is strong. You could try dimming it 10 or 20% and see if it helps.
Overall its not something you want to see get worse, but at this point its not bad either.

It may just be genetic. My next door neighbor has 2 kids, one cute little girl, and one little boy thats as ugly as 3 days in cobb contry. At this point i wouldn’t be too concerned.

New growth looks ok. I wouldn’t worry about one leaf tip. Just watch for progression or color change
