Questions on Transplant Soil

I began my seedlings using a MG Organic Potting Soil in 12oz solo cups (w/ drainage holes of course)
N- 0.10
P- 0.05
K- 0.05

The plants have been growing roughly 3 1/2 weeks and the time for transplant is getting near. I purchased the fox farms trio nutes and I'm wondering if I should mix up a soiless potting mix for the transplant or if it will be ok to continue using the MG Organic Potting once I start with the FF nutes? Will it throw off the nute mix or will it be ok? Either way I feel I should throw some perlite into the mix. Any advice?

use 2/3 potting soil to 1/3 perlite.

as far as the nutes go, the MG soil will be fine. it shoudln't add too much to the mix. just keep an eye on your new growth. if it's nice and dark green you don't need nutes. light greenish add your nutes.

you can go soiless with no harm though.
