Thanks for finding that Homer! Watched the whole thing and I really like this guy's information. And he's recommending the exact same fertilizer that my contact at ProMix said: 20-10-20 from Jack's!
He didn't cover different EC feed rates for different stages of plant growth though.
Since no one sells ProMix HP around here any more I may build my own using vermiculite instead of perlite.
