Dry Ferts? Like Flourish Tabs or something else? I really appreciate all the help everyone is giving me and I'm sucking up all this great info like a shamwow towel loloka so you have ~3wpg of light on top of that thing, you dose flourish 1x/week and flourish excel 1x/week.
a few things to note. you with that much light you need to dose your carbon every day or go for a presurized or a diy system and supplement it every so many days with excel. keep your flourish dosing the same until your green water is solved but then you will probably want to go to daily dosing of flourish until you are out of the stuff and then pick up some dry ferts they are much cheaper and will last much much longer....
