Roots Organic 707-does not run hot and needs additional nutes- here is a quote from the company:
"Roots Organics Formula 707 is a ready-to-use soil created for a special kind of gardener, those who want to control their own destiny. It was designed with greater water-holding capacity, fewer nutrients, less perlite and less pumice, and it contains ingredients specific to large container gardening."
Roots Organic Original is fine for mothers, but would need nutes after a few months.
Just give a low dose of nutes that you would use for veg and they will bounce back in a few days to a week.
I don't check or worry about pH or ppm in soil grows, unless a problem surfaces.
