Stinky: The reason I use the ProMix is because the big commercial grows usually use it. To me that's a good endorsement. I will be monitoring this next cycle closely and keep log of runoff ph. Also I'll be trying a new bloom formula for part of my garden next cycle. Trying the DutchMaster Gold series. According a one long time grower in my area he claims his best yield yet last time using it. I'm not abandoning Fox Farm, just doing a comparison.

Perhaps you may have noticed that Fox Farm is drawing a line through their Ca content of the TigerBloom. I guess they're acknowledging a calcium shortage???? interesting
