Here goes - many organic growers start either building their own soil from the ground up, i.e. buying peat or coir, one, all or any of the following: perlite, pumice and vermiculite. Some dolomite lime (to neutralize the peat moss PH) and some kind of a wetting agent. From there you add your compost or earthworm castings which will be PH neutral (assuming that you're using compost which has been correctly made), seed meals or bloodmeal for the 'N' deal and bonemeal or fish bone meal for the 'P' deal. And some type of rock dust.
None of these soil amendments will cause a change in the potting soil's PH.
If you start out with a professional soilless mix like ProMix or Sunshine Mix, these products are made for the nursery industry. Their mixes are adjusted for a neutral PH at the packing shed.
The humic acids in compost (and earthworm castings) neutralize the PH in the soil meaning that even if you add a tea in the PH range of 4-9, these acids keep things in check.
I know that this flies in the face of conventional cannabis growing because much of the information comes from the hydroponic side of things that got transferred over to soil growers.
There's a plethora of information about PH and organic farming so that you can make up your own mind.
One of these days I'll have to pick up a PH meter and see what's going on around here! Or perhaps I can borrow one from another Oregon MMJ grower.

Great explanation indeed!! +rep
Learning organic is very new to me but also very interesting,any info on these teas and ppm?
Seems these teas are only added every few waterings,whats given between the tea feeds?
