Aquarium fertilizer

Looking for some advice on aquarium fertilizers for my 5-gallon tank. I’m trying to decide between Seachem Flourish Excel and Seachem Flourish. Which one would you recommend?

I have a few floating plants that I’d like to grow faster, and I might add more in the future. I’m currently using Prime, which works well for water conditioning, but it doesn’t seem to help with plant growth. I’m looking for something to help my plants thrive and spread more quickly. Any tips or suggestions?
