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
grey1223 Reviewed by grey1223 on . Raising PH Hi All I'm am using Fox Farm Nutrients at 1/2 their recommended dosage. I have no problems with the PH until I add the Open Sesame. This tend to turn the whole mix in to straight up ACID. PH 4.0 or Lower. I am using a General Hydroponics test kit, and am having to use a large amount of PH up to get it to 6.0 or better. The PH up contains potassium carbonate and potassium silicate. Should I use some dolomite or something ,to up the ph instead of overdosing the potassium? Rating: 5
