A few gnarled leaves

Hey guys so I’m on to my 3rd grow and noticed this for the first time (check pics). It happened pretty quickly to like 3 leaves (yesterday) and I’m not sure why and I’m worried it may spread. Coco is not overwatered so don’t think it’s that. Any ideas? Plants are outdoors. Thanks for the help.

Post a few pics of the rest of the leaves if you can please. I see a few spots on your leaves but cant make out much from this one picture alone. It would appear as though something is eating the bottom side of your leaves, not really spotty enough for mites, but still looks like your plant is under attack. Are you planting in pure Coco, or a mix, what are you feeding and what changed in a the last week?
