Normal dosing is 1ml of each solution for every 10g tank water every day. You dose macro's at one end of the tank and the micro mix at the other end.
I use 3 dosing bottles as I put nitrates in one dosing bottle, phosphates and potassium in one bottle, then micro's in the 3rd bottle. This allows you to better dose ferts to the needs of you tank.
I test for nitrates and phosphates each week right before my WC to see where levels are at the end of a dosing week. This then allows me to use more, less, or the same amount of nitrates and or phosphate/potassium mix for the next weeks dosing. In a planted tank you want nitrates at 10-20ppm and phosphates at 1-3ppm. Micros you always dose at the same amount.
Also if you have hard water with a gh of 4 then you don't need to use MgSO4, magnesium sulfate. Most tap water has plenty of magnesium in it for plants.
