Let the tank settle for a bit, but yes I would change the substrate; I know from my own experience that not being satisfied with the substrate will always cause you to think the tank isn't really working. I've been there. And for inexpensive, nothing beats a bag of play sand, Quikrete Play Sand from Home Depot or Lowe's. I have it in 5 of 7 tanks now, and it will likely be in the other two before this year ends. A bag of 25kg is about $7 or $8, and you'll have some left over which is good.
I asked about the 6 weeks because the plants look good to me, and if you had put this together a couple days ago... but six weeks is time for things to show up, so I think it's fine.
