Greetings. I'll be growing outside soon using FF OF cut with some perlite in 5G fabric pots for WW-A's.
My irrigation system's well water is very low PPM (almost RO like clear), but the ph is in the mid 5's based on current conditions. Since it is difficult to ph irrigation water for an outdoor grow, I may be forced to add lime into the soil to keep the ph up in the mid - 6 range.
Should I lightly sprinkle a bit of lime on top of the soil so the irrigation can bring it down into the soil, or should I mix XXX amount of lime into the soil when adding perlite?
This seems to be a guessing game which I am not particularly fond of.
