My pH is slightly above 7, but I know my meter is off. I have pH down being mailed to me and new buffer solution for the meter... won't have it until Friday unfortunately.
If your not sure that your pH meter is working properly, dont even bother with it, and dont bother with ph down either.
If you do have a pH issue, its minor. Trying to correct it could cause more harm than good, if u dont have a proper meter to know precisely what your doing.
Soil in and of itself is an amazing buffer, (even more so if your in organic living soil) and provided your starting out with a pH neutral water (RO or distilled or even purified), free of contaminates, it's very unlikely you'll need to worry about pH, so long as you arent adding excessive amounts of nutrients every time you water.
I personally do not own a pH meter, and although I'm sure I do occasionally have a high/low pH, I never have issues, because I use a clean water source, and only provide nutrients when the plants leaves tell me to (not when the nutrient schedule tells me to).
Growing ANYTHING (let alone marijuana) is a lifelong hobby of making mistakes, and then learning what you did wrong, and how to fix/prevent them. As long as your actively seeking out answers, taking constructive criticism, and applying it as necessary, you'll be fine. No matter what though, you'll always have a few kinks along the way, you just learn how to better handle them.
