My opinion, for what it's worth.
Transplant into your final pot size. Fill pot with good mix of soil and amendments, such as ocean forrest and pro-mix, 2 to 1 of pro to ocean. Add amendments, such as alfalfa meal for ph, crushed oyster shell for ph and cal-mag, chicken shit, bat shit, and I personally like crab meal. All of these should be light as you can and should add again. I would also consider mixing some permits in with your soil mix to. I would also strongly recommend a fabric pot. Water in and watch it go.
