Ok good to know it’s my first grow they just seemed kinda odd looking to me I didn’t want it to turn into something else
I personally think they look vigorous. My buddy gets much wrinklier plants in veg like this, and they always veg faster than mine. He uses silica and hortilux t5's in dwc. I don't think it's rootbound. I get leaves like that too, but ONLY after transplant.
My plants are definitely more likely to be rootbound (1l airpots) and they only get leaves like that if I put them in larger pots. In fact, I swear that my pot size gives me tiny fan leaves.
I personally think when the leaf looks like that, they are just preparing to be the size of a baseball glove, like the lower fans in your pic. I think it looks good, maybe a little tip burn if anything, which can also be kinda good.
I wouldn't change anything.
I'm not certain about any of this, but I am always happy to see leaves just like that.
