pH over time
I recently was recently reading something about micronutrient problems. pH was implicated - too low or too high and some things wouldn't be available to the plant. That's consistent with everything I've read here and other places.
But then the author wrote that the pH in containers can drop much more quickly than we think, such as in weeks to a month or two as the things we've added to increase the pH are leached out.
So, I'm curious....how quickly are things like lime leached out of the soilless mix by watering? Does it matter the type of lime you use (some is sold in tiny pellets and dissolves very quickly, some is large and dissolves more slowly)?
