Thanks for the reply, Minnesnowta. I think I'm going to ask FF directly about the separation thing.

As far as feeding goes, what I was trying to ask was how much do I actually give to my plants once I have the solution mixed? For example, say I mixed 1 gal. of solution as directed in the FF feeding schedule. How much of that 1 gal. should I add to each plant given they are in 2 gal containers? Like I said, I am awful at nutes, and usually either deprive my plants or poison them. They will be growing in FFOF and I most likely won't be adding nutes until week 5 flower, as they will be going from 1 gal containers to 2 gals when I begin 12/12. I hope that makes sense.
