Yeah, I broke out the drop tester, and the pen is off..... Got buffer today and hope to get the pen re-upped tomorrow.

Most everything is still looking good, so I'm hoping this little thing isn't gonna blow up in my face!

When I say "Little thing" I believe for the last week or so the Pen has been giving me off readings leading me to lower PH below my target of 6.0. I have no clue how low they got, or how low my run off is since my pen hasn't been recalibrated yet. I've only barely seen any signs of a problem with the plants, and that might be my imagination ATM.

The clue to something being off was the water was taking almost 2x the PH DOWN to adjust as it was a month ago,... LOTS of red flags went up! :wtf:


I went back an pulled all the paperwork on the pen,.... wow,... I should have read this when I bought it!

Like I said in the first post of this thread,... Still kinda new to this game!
