Isn't calcium considered 'immobile' and thus of little use in the soil if needed quickly in the growing tips?
They say a calcium foliar is the way to deliver to tops.
And I do use sugars (molasses) when brewing microbial tea. I imagine it bulking up population which will spill their guts in the root zone. Like below frigid said, I add the tea to a super soil.
Once a seed or clone gets its legs (3 weeks) it can take the super soil.
Through up-potting to 3 gallon pots, all the way to harvest I only add the tea and water.
