Panama what test kit are you running?
I could never get my hands on a narrow ph drop test kit 4-7, I've seen them in strips and there is narrow ph drop test kit 4-7 listed in the 2011 hydrofarm catalog that I got exicted about but it still is not available, it is nice to have a backup to a meter.
I been reading ph drops for 40 years? I always went for pea yellow and I never knew how far I was off till I got a digital, that link I sent is a pretty nice meter for the $$ from a good seller. I purchased that and the matching ppm meter for the same $26 and I'm real happy.
