Answer for How to Raise my PH with Plot Start

PlotStart works to release the positively charged atoms in the soil which “boot” Hydrogen atoms off soil particles which causes the soil to be acidic (low pH). Our research indicates that using 2.5 gallons per acre would sufficiently boost pH, and more importantly provide instantly soluble calcium and micronutrients to the plant, however, at that pH you could look at up to 3.5 gallons per acre. 
Timing of effectiveness depends on soil physical property. For instance, it will likely take longer in clay than silt or loam soils. To be safe, you should be able to see a noticeable increase in pH value and calcium levels within 45 to 60 days.
Exactly correct on the mix. Just take 25 minus how much PlotStart you put in and then that’s how much water you need to cover an acre.
