r/o DI water question

I just ordered a r/o DI filtration system (finally)

Do I need to use a product like R/O right or Seachem's replenish or equilibrium or can I just mix in a certain amount of my tap water to make it have enough nutrients in it.

You can definitely mix your RO water with tap water to replenish some of the nutrients that are stripped from the RO water.

Would that do the same as adding the additives or are there specific minerals in them that would make it more advantageous to use them?

All I know is this week I ran out of RO water, which is what I started my tank up with, did a 15% water change and now I'm having problem with algae. I suspect it's because of all the phosphates in my tap water. Thankfully, I just finished installing my RO system.

You can do it either way. Which way is better depends on what's in your tap and how demanding your flora/fauna are. The nice thing about the additives is you can be assured that what you did last time (added X in) will be exactly the same even if it was a year ago or even in a different city.
