As for liquid ones, I use Flourish. There are several different kinds for providing different nutrients, but the main one is called just plain Flourish, and it has all the standard macro
and micro nutrients. I've also used the API brand, but I didn't like it as much as it stained my water yellow.
not true..Seachem will even argue that.
Flourish is just micros and trace..there is no Nitrogen,Potassium,Phoshate (the main 3 macro nutrients) in it..And it doesn't hurt to have a carbon source;either DIY or pressurized CO2 or Excel
The Seachem root tabs are good one's
The Flora Pride and Leaf Zone is just an Iron boost basically,with some Potassium in the form of potash.Never seen the water turn yellow from the API brand;the only liquids that the turns water yellow are the blackwater extracts like Tetra Blackwater Extract,Kent Black Water Expert etc.
