Hi weedhound, thanks for your time.

The DNF Bloom formula I'm using has 2.3% calcium, and the fortifier has 0.5% magnesium. I'm going to try the CAL-MAX at half strength at first and drop my ph to about 5.5.

My ph up and down are from DNF as well, not homemade. I also use Grotek's up and down as well.

Thanks again for your assistance.
