I don't have any fertilizers for my planted fish tank. I have heard that seachem flourish is a good one. Is that a good one? Should I go with liquid or tabs?I have floating plants as well as rooted plants.
Yes, Flourish Comprehensive is a good fertilizer. Lots of ppl here use it. You at least need the liquid fertilizer as for the tabs that will depend on what rooted plants you have?

Do you still have Eco complete as your substrate?
I had this substrate when I first started out and found after time I still needed root tabs. Your swords and Vallisneria will benefit from the tabs. The rest will be fine with just liquid fertilizer

Another possible issue maybe your lights? What type of bulbs do you have? How old are they?

I do have that substrate still
I would go with just the liquid for a few weeks and monitor the plant's response. Liquid is essential if any fertilizing is necessary, for any plants; some of the nutrients are only taken up via the leaves, so not having them in the water column is not going to help much. And the water naturally gets down through the substrate, carrying nutrients with it, so all plants will benefit from liquid.
As Boredomb mentioned, some plants may need additional substrate fertilizers. These are plants we term heavy feeding, such as the Echinodorus (sword) species. I use liquid (Flourish Comprehensive) in all my tanks, plus in the two with my large Echinodorus bleherae, E. cordifolius and the Tiger Lotus, I use a tab next to each plant, once every 3 months. The species mentioned do show increased growth from the tabs, compared to when they only got the liquid.
Vallisneria should be fine in Eco-complete with regular liquid fertilization. It's primary need is for "hard" minerals, as it uses bicarbonates a lot and thus thrives in harder water.
