One month progress pictures

Hello everyone! As a new grower I just wanted to get the advice of some of the experts here on the subreddit; how are my tomatoes looking? They’re about 4 weeks old. The green giants are about 3.5 inches tall. The rest are about 2.5 inches with the exception of the Mexican midget which is about an inch and a half. My main concerns are the leaf curling in the green giant and the brandy boy. Does it look like they need anything? Thanks!
