Ok, I have a serious question that I need help with. I have been searching the Web, all that, trying to find answers. I can't find it.

Is an aquarium pH tester kit accurate to measure pH with on a plant?

When I tested the tap water with it, it read 6.8. Good. But when I measured it with FF Big Bloom, it said 7.2. And when I tested my runoff after watering with nutes, it said 7.8. So is the fact that the test is color coded messing it up? The water is no longer clear once I put the nutes in, or check runoff. So is the brownish color of the tested liquids messing it up? I have to know. I am almost to harvest, and I believe I am in pH lockout, but have no real clue if this test kit is accurate. I can't find a pH pen in my area at all. Closest one is 142 miles away in the big city. Help!
 
i have used this type of ph test, they can be very good, especially for the price
but heavily colored outflow can be a bit of a challenge, if its turbid, filtering may help
your water sounds pretty good, if you're near harvest and all is well, then you're probably dialed in
 
there is one that works wonderfull made of cabage google cabadge ph tester just match the coulors to the ph to make a scale then it works wonderfull it has every coulor of the rambow:P and everything in between so if u fine tune it it can be very acreate and cheap as hell
 
Thanks for the replies, you two. I think I will hold off on trying to use my aquarium one again, and just have to get a pH pen on payday. Seems like the best bet.
