wrinkle growth

I am at week 2 of veg.. using 6" grodans and perlite as medium. I water once every 3 days, ec around 1.4 ph 5.8.. water temp 70-72, use ro water and house and garden nutrients.

The leaves look kind of wrinkley.. I have noticed with other crops (just switched to hydro.. 2nd grow here) in soil the new growth up top would like like this but the rest of the plant would look normal.. noticing more of the wrinkled growth though. ideas what this may be from?

thanks!!

Wide temp fluctuation...ussually the colder temps will do it from my past experiences. Plants do look healthy though, props to you.

that could be, temps are 70 to 79, usually topping off at 77, sometimes hits 79 in veg room. Flower room is 69-75, sometimes hitting 77.
