Hi
First post so hi to all. I have the liquid ph test kit and am a little confused by the 'readings' I am getting. I checked the solution last night with the ph tester and I would say it was reading about ph level 6. However, I left the solution in the test tube overnight and when checking it just now it has changed to quite an orange colour (ph of 5 or less). How is this possible? This ph test kit is about 5 years old (not been used since my last grow), does the kit have a life span. I will go get another kit asap but in the mean time can anyone explain why the ph level in the test tube would change so much overnight? Many thanks
