Superthrive is 1 drop per gallon listed right after ph level as ST, sorry for confusion. As for Nutes, I have been using Lucas Formula I found on this site and tweaking it a bit from GH's site. Had not been using GH Grow since Lucas stated it wasnt needed since Micro gives plenty of N and didnt want trees inside of cabinet. Pics will come tonite as I am about to run out the door to work.
