Newbie : what is this leaf trying to tell me?

Hi, this is my second grow. This time I’m using clones in rock wool only. I turned them 2 weeks ago but one plant on top of plant has weird couple of leaves. Feeding them nutrients 2 part, 1000-1100 and flushing once a week. Indoor grow in tent, super powerful leds,
Any suggestions would be appreciated!
Regards sharon

Should mention it was only this leaf on plant found at top, rest of plant leaves look fine and the other plants in room look fine too

Could be just genetics. If its the only one I wouldn’t worry too much about it.

Yeah sometimes leaves just grow all twisted, but I think it looks a little bit like light burn or heat stress and with you saying it came from the top it fits. Just keep an eye on your light distance just in case it is.

Could be a few things: Grew out too fast and they will look crazy when it happens, wind damage from the beginning of the leaf grow if you are using fans, light issues can cause the plant to grow too fast as it tries to stretch too.

I strongly believe this is genetics, although rare the twisting with the light color can be a boron deficiency. Again this is rare. What’s your medium, how olds your plant, have you fed nutrients? What’s your runoff and ph?
