I have been clean for 3 weeks now, I work as a roofer in Florida so I sweat a lot and I usually drink about 1 and a half gallons of water a day. But the second line is waaay to faint for me to be sure about it.
Any line, no matter how faint it may be, is still a line according to the tests I've taken. If you can see the line without having to turn the test or look at it from a different angle, then you are good.
No you are not good that line says you are positive for pot the other line is way to light i have sent that one in the mail before and they said i was still positive
