Hey, Blue. Yeah. I've been feeding with tap water with a bg EC of < 0.2. Some people had success with RO and megacrop, some had to bump up EC to address cal/mag issues. So it seems I gotta feel it out.
I'm thinking for future feeds I calmag my tap up to 0.4 EC (~3ml) before adding other nutes, or might just bump up the MC as many do. Still waffling.
As for a foliar, I'm in a pickle and need to let 19L pots dry out a bit more than normally advised. The plants are already under fed. I thought maybe a calmag foliar app could give them a boost until their next feed. I thought maybe there were some signs of cal deficiency. Not possitive.
