I'd think so. Looks like the soil probe is a couple whole points off. Beware of trusting that it is 2 points off at higher ph values though. It might not be a sliding-scale difference at higher ph's. (might be one point difference, might be 3 points difference)

I'm formulating a plan after reading the e-mail to compensate for the issues of lockout in lower ph soils. Might even revert back to Grow Big instead of Tiger Bloom, and I am stopping the Cha Ching altogether. (PO4 tollerance issues)

<sigh> Learning is such a bitch sometimes... :jointsmile:
