I would. Adding new soil should also provide new nutrients and save yourself a trip to the store.

Any suggestions on type of soil to use ? I'm in Canada and we don't have Fox farm soil.

I'm not sure about canada, if you have a hydro store ask them what they suggest as far as name brands. Or make your own.
Easy recipe
Organic Compost, Peat Moss, Perlite, Pumice, and Worm Castings.

I was given 7 bags of that crap for free lol, that soil is lacking lime worse then any other bagged organic I've ever seen. Can't go too far without food either

Get your transplant pot ready, mix in a tablespoon of dolomitic lime per gallon of pro-mix ultimate V/H, LIGHTLY water it and let it sit for 2 weeks before transplanting.

It seemed to have gotten worse. I'm not 100% sure but I think it's a nitrogen deficiency.

Looks like it.
