Hi if you have a low watts lights the plant will take longer sorry I noticed you said your lights not great in other questions but no dairies to check good look and plant looks healthy now but watch for nanners and hermies
So I just did a run of NL Auto and they went into preflower day 21 and day 26 , it's up Genetics and the plants environment and feeding , but it shouldn't be to long ...... happy Growing 👍
