"I have never seen a case of CA deficiency in cannabis"------Ed Rosenthal
Cal-mag.....probably the most overused unnecessary product in the growing world.
I run small batches using Everclear Approx 18 g trim
20 second soak
30 second swish
Triple Filter
Cook @ 110 deg
Finish purge @ 150 deg
Move to parchment
My experience with Everclear vs Iso is...
Everclear filters faster than Iso
Doesn't stink like Iso
Doesn't taste like Iso
When purged correctly, end product is glass-like and stable at room temp
