You CAN wait, but 3 foot sounds a tad tall. They will finish at atleast double that size, so you gotta be sure theres enough room in the grow room.

A plant may increase in height by less than a third or more than triple after going 12/12, depending on its strain, the growing method, the growing particulars, and how tall and healthy it is at the time.
