AN 2.5ml Big Bud and B52, 3.5 ml Grow/Bloom/Micro

I have noticed AN like to stay around 6+, compared directly with Green Planet hydro fuel, the AN was consistent with being higher. Cal Mag added to a preexisting nutrient solution can cause pH spikes, and so can bacterial colonies on slime.

edit: also, taking reading in the bubbles is bad.
 
These are the properties I would love to metal detect!
You'd be surprised at some of the stuff that's been found down in the village I'm originally from.
The village was built over a Shawnee Indian village, has been a part of the Revolutionary War (my ancestor fired the 'shot heard round the world, haha), was a stop on the underground railroal, was a canal town, then a WW1 and WW2 industrial town...
Now it's a meth addicted shithole.

We've found grape shot, cannon balls, human remains after a flood...

I've noticed that without anything besides AN it seems to hover around 6.2. For it to be this high was rather surprising. It may very well be the container, and I've already ditched it in favor of one that has only ever held distilled water.

Weird. Thanks for the advice!
 
the pH probe I have is supposed to compensate for temperature... The light makes sense, though, since it's exposed to the lights, where the tank is black and quite dark.

Just do an hourly reading for a while...see if you can pick up what is affecting it...:headbang:..my grow cupboard was outdoor...so I had big swings..
