There isn't enough info here to give you any kind of meaningful answer. I suggest you read the stickies in the fertilizer section and try and absorb a lot of that info. I'm trying to say this as unoffensive as possible (not my strong suit), but this looks like a question from someone that's brand new here and you have over 400 posts.
Your plants need light, CO2, nitrates, phosphorous, potassium and an assortment of trace elements and iron. (The trace elements typically come mixed and are dose together) Plants will only grow to the level of the least available of these. You have to provide all of them at acceptable levels.
In order for someone to give you a meaningful and accurate answer they are going to need more info like; How much light, tank depth, general types of plants, how heavily planted, substrate, water parameters, livestock, frequency and amount of water changes, how many root tabs, how often.
Just because i have 400 posts doesn't mean i know everything lol.
I am always trying to learn new things to help me keep my animals healthy and thriving.
I am new to CO2.
My tank is a 65 gallon with a 20 gallon sump and its 24 inches tall with a fluval 2.0 planted tank light on it.
I have only low light easy plants right now. Just crypts, anubias, and dwarf sag. I want to get the CO2 down before i spend a bunch of money on the high end plants.
My tank has one little red eye puffer in it and about 10 cory cats.
I have put osmocoat tabs in it one time since its been up for the past like 2 months.
I dose florish excel almost every day.
I would like to know whats the best ferts out there. Should i do dry and liquid?
Is liquid good for all plants or just for plants that take most of there nutrients from there leaves?
Now have anything to add?
