How to tell if my aquarium plants are doing okay?

Hello!

I've planted my first aquarium and I'm very cutie on how to do this.

Currently inhabiting my tank is a small lawn of dwarf hair grass. It came on a mat. Red foxtail for my guppies fry, a small Java fern, a banana plant, staurogyne repens in the foreground, golden creeping Jenny, and ludwigia repens.

I planted the staurogyne repens, the banana plant, and the Java fern first. They have been in there for 3-4 days. I haven't seen very much melt. Just a little on the Java fern yesterday and no more today. Everything is green.

Today I added the foxtail, creeping Jenny, dwarf hair grass, and ludwigia repens.

I have two T5 bar lights that give off 36 watts all together. My tank is a 10 gallon, 20x10x12", I have Eco-complete substrate and I inject my water with liquid co2. I also use seachem flourish. I de-chlorinate my water with seachem prime.

For fish, I have three adult guppies.

Does my setup sound okay? And how do I know if my plants aren't doing well? This is my first planted tank and I'm worried about them not rooting and stuff
