Don't pay any attention to HungryMan. For thousands of years these plants have been just fine without RO water. I have no idea about Maxi Gro but if your plants look deficient in Cal or Mg, then give them a little and see if they respond positively.

from what i know, the maxi series doesn't have a good amount of cal/mag so it needs to be added. cal/mag is its own nute. maxi gro has nitrogen, potassium and potash.. if it has cal/mag, they will be trace amounts..
