Autoflower problem

Hi everyone I'm a first time grower currently growing stardawg auto under a 600w LED temperature around 24-27° with humid stuck at 40%, humidity won't go up no matter what I do, I'm on day 18 Of my grow so far I have fed 1L of water twice with 0.25ml of bio grow, I'm growing in biobizz light mix in 5 gal pots, my 2 questions are 1. Is my plant normal size and 2. 1 or 2 Of my leaves look a bit curled up which I don't know if it's normal

Patience, every little wrinkle isn't necessarily indicative anything. As young as she is, you'll end up losing those leaves anyway. Let her be. Just my opinion. I think she looks fine.
