Hey Smoker Happy FreeWeed day
I didn't know of the accuracy of using baking soda as ive never used it so I couldn't comment on it either way
I do for myself even 30+ yrs ago never did ph any of my soil plants or check ph of any plants in soil regardless of what kind of plant
and if it does need nutrients always best to use organic stuff
throw some earthworms in the pot use some fish emulsion etc...
these things I did 30 years ago lol
but lately I just buy decent soil and I still don't check or mess with ph
I would think most if not all these soil manufacturers know that most plant require soil in a certain ph range
and to have a good soil that will sell and be successful has to be within a certain ph range to be good soil
unless you make your own soil in which case you will be responsible for yourself what kind of natural nutrients that will release on its own you can put in there and how alkaline or acidic you make the soil
our plant requires slightly acidic
