Try adding calmag first,then mix well before adding the other stuff.you might see a higher pH this way.you could also add like 5 or 10 gallons of tap or well water to the res if it's not super messed up.then your water)nute mix won't be so out of whack when ya add those nutes.i would still mix the calmag first in either case
I have grown with the AN Sensi line. It has their “ph perfect” technology. I was having some issues with it and I called their growers line. They said do not adjust the ph. The special chelates and surfactants are designed to “feed” the plant at a wide range of ph. He said if I had a ph anywhere between 4-8, I was good. When I added ph adjusters, it was fighting with the Sensi nutes and causing leaf curl and some spotting. It all cleared up when I stopped adding ph up or down.
I stopped using AN after that. I want more control over what’s going on in my res. But it would be great for someone that doesn’t have a ph pen, and is just getting started in growing.
Well just check you ph daily in Res and take logs pretty quick.
You can use armor si for PH up. I'd ph to recommend soil level. Soil does buffer. But I try not to jack up the PH in your media. You'll have all sorts problems which are pain in the ass to fix.
The name of the game try to get through veg and flower without any issue and your prob have a decent yield.
