What was your target EC/PPM?
This year I started my outdoor plants with organic soil and slowly transitioned them from water-only to a semi-organic diet for more precise control during flowering. Basically just weak nutrient tea + small doses of synthetics.
Anywhere from around 0.7 EC up, usually lower ECs fell into an acceptable range. The higher the EC the lower the PH started out. I'm mixing in RO, so no existing PH buffers.
