If it's true that you use 10ML/L of all 3 General Hydroponics Flora Series then your EC would be way higher than 2... :P

My formula for my 50l tank is 30ml=.3 EC. This ratio works great. I use the 3-2-1 proportions to the 30ml dose. Ie right now I’m doing an 8x30 dose to get me to 2.0 EC. I add a double dose 60ml daily these days as the girls are drinking like sailors.
