You guys Ph your rain water?

I tested some rain water i collected. Found it was fairly acidic, around 6.0-6.2...

Should i adjust it up some or leave it alone?

I've always collected rain water and never pH'ed it. Don't get me wrong, I have pH down and up and nice meters and calibration packets but rainwater typically is acidic.

I use dolomite lime in my soil @ 1 TBLS/GAL.

Wouldn't worry me at all.

Then again, if I was using a hot soil like MG or something, I might ph it up...

I run mine through a homemade carbon filter and it is generally 7.0
