I dont know what your reasons for using the method are im no judge or anything but personally u picked the hardest way to grow that allows minimal room for error. An aero system would have been much better in your case to work yourself into fog techniques. Doing fog for your first grow or for a beginner is like jumping in the deep end and you havnt a clue how to swim. It's a fun idea to do the best way of growing, but it means nothing in the end when the results are crap. But hopefully u can pick up the pieces and get this to work. I know if u can do this trial run and get all the kinks worked out, the next will be better and so on.

I do believe most people use two foggers one for plain water and one for nutes, that solves the roots drying up problem and over fert. The thing with fog is u havnt realized is that PPM's play a role and also how often they get fed, because they will just keep sucking up nutes at a high rate in fog, unlike other methods where the roots take time to suck up the nutes.
