Dude post some pics so we can take a look. It could be some type of nute deficiancy or under watering. post pics and are they in soil or hydro?

my leaves on one of my coco substrated plants looks like that recently too, I am wondering if enough air has been getting to the roots? That stuff stays so hydrated I am wondering if that leaf formation isn't a sign of overhydration and not enough air to the roots... any thoughts?

I have never used coco, I am thinking about it but I dont know much about it. I had some thing similar but it was due to foliar feeding and the lights. I wish I had better advice man.
