I have no first hand experience with ocean forest, I hear that it runs a little hot. Maybe you would be well served cutting it with some of the light warrior you should have left. I use small peat pots for my seedlings and the moment they show that yellowing it's time for me to transplant. They usually take off in a matter of days.

Also, when you do transplant (soon I hope), I would water a bit first so the soil keeps it's shape and cut down the sides of your cups. Do NOT try to handle the plant itself. Fill your second pot with soil and put the same small clear cup in the middle to create a negative in the new soil. Drop your rootball in and voila.
