We do have an under counter filter, but even the regular tap water is >500.
The big plant has taken off, and now I am about few days into flowering. My question is, how soon should I transition to the bloom nute recipe? The formula you gave me above was basically 3/2/1 ratio. Should I do a transition of 2/2/2 a week or two before going to 1/2/3? Also, any tips or tricks with any other additives/flavorings? Is there anything aside from nutes that I should add in somewhere down the line? Thanks again!
