With RO water that's 0 ppm and has a pH of 7..... with the 1tsp of MaxiBloom per gallon... what does the pH come out to? (without adjusting it or adding anything else).
I don't want to buy a bag of MaxiBloom just to do this test, so please help out if you can.
p.s. 2nd part of question would be, what is pH after adding normal rate of Cal-Mag?
Can't help you with the cal/mag question, but I just checked my pH with straight bubbled tap (9+) and 1tsp/gal MB after it's been mixed,settled and remixed and the pH came out to dead-balls 6.
So, in my case, it's dropped pH by just over 3 pts.
