Rainwater and fertilizer
Living in Florida, the tap water is not good. Been collecting rain water (hardly rains) and wonder if it is really necessary to use a special fertilizer designed for RO or rain.
I have used RO water when I lived in NY with MSU for RO. I don't have RO in Florida so am using rain water.. Does it really matter? Is it a pH thing or can I use any fertilizer with rain water?
Trying to simplify things...
