If this is day one?, it won't be doing much for a few days, this is normal.
I would start a starter with 100g flour 100g water, for the first few days, you need to throw half away every day and top back up with 100w/100f, keep doing this... after a week or possibly longer, you should see good activity in the starter, lots of bubbles.
Once you get to this stage, you can start to use. You can then start using the starter and not throwing it away.
