I have run a few combo's over the years(GH Flora trio, Megacrop) and they worked well.
I currently use Jacks 3-2-1. Very simple to adjust and inexpensive.
I'd also suggest adding some silica to boost stem vigor.

How's that Jack's working for you in DWC? Is your PH pretty stable? What kind of water do you use with it? Weed quality must be the same right?
