So I've been having the most violent pH swings, pretty much exclusively to the acidic side, so I've been using pH up like a madman. I find my pH drifts down a full point from 5.8 to 4.8 almost twice a day. I am running an areoponic system with GH nutrients and RO water. I do a rez change about every 7 or 8 days. I eventually ran out of pH up and decided to try baking soda because I couldn't make it down to the grow store. Interestingly I found that the baking soda really seemed to stabilize my rez solution. I stopped having those huge downward drifts and now actually have to use pH down because the solution is to alkaline. I do realize that over the course of a week or 10 days, as the plants consume certain nutrients the pH switches from drifting down in the beginning to drifting up as the week is ending and it's time for a rez change.
So I'm wondering if the stabilization I experienced with baking soda is a coincidence? And Are there reasons why baking soda might be bad, because I feel like incorporating it into my rez, maybe not replacing pH up entirely, but using the two in conjunction. I just want to make sure that it won't encourage harmful algae or cause lockout.
Lol! If you think this is a nutrient problem i reckon 100% of hydro growers would tell you to avoid these crazy ferts like the plague, violent pH swings!!! Used whole bottle of pH up!!! Baking soda stabalization!!!
What logic is there to your advice? Drop the ferts or look for what else swings pH wildly in Hydro!!! Getting bored now!
