The second color sounded great on paper but it doesn't work and the manual says it doesn't matter anyway. Excuse me? The second color is the only reason I bought them. The top color isn't much better. It differs from my drop kit anywhere from 0.5 in the acidic range to 1.5 as it approaches neutral.
I stuck with the aquarium test drops. They kept my marine critters alive and those guys were far more pH sensitive than any weed.
Note there is no pH number at which all nutes are available. A small pH swing is better for your garden than a constant reading. More important than today's reading are the readings of the last three days read together. Are you going up or down? Is it consistant? If it is, you can plan around that. I feed slightly rich. This raises my EC and drops my pH. When the res drops four gallons, I add back straight tap water which lowers EC and raises pH back to original levels. In between all that I get a pH swing of 6.0-5.6

I know someone has mentioned some very accurate pH strips.. I just can't find them with the search function. People mention strips often so it clutters the results.
I think I found some narrow range ones. I really want these to keep my pH meter in check. Using them periodically to ensure my meter isn't lying.

I think that diff papers cover diff "narrow ranges"
look for the 4.5 to 7.5 (or similar) range
