LST looks okay, can't see anything out of the ordinary.
Green looks good, when theres too much nitrogen leaves get dark dark green.
I personally think its a bit early to use zym
I usually use it when i'm entering flower because it breaks down the older roots to give live to new ones.
Never tried it early on, could work I don't know.
Leaves don't look too twisted, just looks like they're rearranging themselves looking for light, they should start looking up and straight in a couple of days. 😀
Happy Growing! 👊
