dunno where you are but i hope the length of daylight hours are getting longer for you not shorter. you need 16 hours at a minimum i believe to keep from getting hermies. 18 hours would be best with 6 hours of dark. you probably need to start there at least.
at 4-5 days old not much to tell you other than no ferts yet and dont over water them. they are little they dont need a ton of anything right now.
