    If you aerate your water for a day or two before you use it PH will be more stable in the reservoir to a point. It precipitates some of the calcium carbonate. When the plants transition from veg to flower the roots will exude substances that will drop the PH like a rock. In the soil this action feeds the micro organisms that provide potassium to the plant stimulating them to provide more - cool huh. Not good in our reservoirs though. This will happen for a couple of days and stop. This is your clue to shift to full on flower nutrients. In autopots if you have big swings you should try mixing your nutrients a few days ahead with aeration then a final PH before going into the res.

    I think this is a fairly good answer. If you want to run organics/carbohydrates in this type of system like Autopots, eventually you will cause a lot of bacteria and microbe growth which can cause pH to fluctuate. So the answer is to either go sterile, (which you lose a lot of the benefits of microbes), or not use the Sweet Candy in the first place.

    You cite the only options for using Sweet Candy with AutoPots as either going sterile or not using Sweet Candy. But how about manually adding Sweet Candy (and/or other 'organics') in each pot's rather than the main reservoir?

    Thats what i figured. In the future I may use Bill's idea, for now I am am setting ph to 5.9 every 2-3 days and letting it rise to 6.3 before adjusting.
    Also been cleaning lines and res once a week, no issues so far beside the ph moving and a odd smell if you stick your head in the res
    If I left them alone for more than 2 days Id probably skip the sweet candy on that fill
