Blue Cheese & Sour Strawberry Barney's Farm

Curling is usually a heat/humidity issue. Too hot or too dry or both. In the second picture it almost looks twisted, which can be an early sign of a pH issues.

early leaves.. meh. if it is healthy otherwise, you can ignore it. if you want to dot your I's and cross your T's, make sure pH is proper. Oscillating pH can cause variance in growth rates, that results in 'wavy' leafes, but this sort of thing can simply happen to the first 1-3 sets of serated leaves. if new growth is clean and normal, all is well. This plant looks fine.

Nothing to worry about really, but it does need to go into a bigger pot asap.
