Looking forward to the eco feeding schedule although it´s just silly to skimp out!
TaNg, the AN hobbyist bundle should be a good start right? Voodoo juice, big bud, b52 and overdrive. You use a lot of those ingredients!

Oh and carboload of course!
Oh, and a few questions, your tap water ec is 0,4 and you said maximum feed is 1,8, is that 0,4+1,8? My tap ec is 0,22, should i increase the feed a bit more? 0,18 or whatever it may be?
