Hey
@Mañ'O'Green , on the new MC 1-part I have a question in regards the numbers you posted.
Are you adding cal-mag to RO water until it reaches 100ppm? Correct? Do this first then add Epsom/MC.
Would leaving out the cal/mag and using a cal-nit product and more epsom fill in the N and Mg holes without adding too much ca?
Cal Mag add until RO = 100ppm
N 77 (100-250)
P 28 (30-100)
K 101 (100-400)
Ca 114 (100-220)
Mg 43 (50-100)
S 61 (40-500)
