Cal Mag Plus Question

[MsBotwin]

I am using Hydrofarm's Emily's Garden for my first grow. It only takes 2 gallons of water at a time. I am using GH Flora Series Nutes. Since my res is so small and I have well water run through a softener, I use distilled water. At first, I didn't realize I needed to add cal mag until Monday. I got some and added it to my res with top off water. Since then, the ph shot up from 6.0 to 7.5. I have managed to get it down to 6.5, but how do I control this? Just add ph down every day? Any advice would be appreciated! Thanks .

Try a whole res change first I use all GH products and add 1 ml / per gallon of botanicare cal/mag .. My PH is pretty stable but try a whole res change use GH online nutrient calculator.

I will try that! Thanks. I do use the online nite calculator for my nutes. My ph was always a stable 6.0 before I added the cal mag plus, botincare, same brand as you. Rep + for the reply! Thanks again.
