Roberta,
Here is the info. Trying to be as accurate as possible.
I used one quart of RO water. The pH strip said 7 and the meter said 6.73.
I added 1/4t of FeedMe!. The pH strip said 5.0 and the meter said 4.4. I dipped the meter in the 4pH calibration solution and it said 4.02. The pH strip said 4.
The only difference from my earlier measurement was 3.75 vs 4.4pH.
I noticed one detail. My FeedMe! is neither blue nor pink.
It is mostly white with a sprinkling of Green pellets. The green pellets are larger than the rest of the stuff. So like brazil nuts in a mixed nut can they float to the top.
Maybe the green pellets are high acid? If so, maybe my first scoop had more of the green pellets than this latest scoop. In any case, the result is far too acid for my taste.
In any case, since my fertilizer is neither blue or pink it is a different breed than normal FeedMe!
I am going to call up the company and find out what is going on...
Cheers.
