Passed home pee test BUT!...

Hey guys, recently iv'e been doing a lot of research about diluting pee for a home pee test. I used to be a daily smoker for about 4 years, up until the end of last summer where i stopped smoking completely due to my family being up my ass all the time. On new years eve however i got the smallest amount of amnesia haze from my friend (about 0.2gr) just to celebrate the new years. It was the smallest amount however i did get stoned, and two days ago (3rd) of January my mom insisted on doing a pee test, although she hasn't for almost 2 months now. I tested positive for THC two days ago which i was really surprised because i only smoked the smallest amount. However i denied it completely and said the home tests aren't reliable at all and that they should test me again.

So we agreed to test me every two days for the next week just to make sure. Today which is exactly two days after my first test, i diluted my pee with about 2 litres of water and a Powerade, and also consumed 4 pieces of Vitamin b12 (for the yellow color) 2 hours prior to my test, AND IT WAS A SUCCESS!, HOWEVER, my mom was very curious because my pee had NO smell and was almost transparent. I don't understand why my pee didn't go yellow after the vitamins, and unless i find a method to dilute my pee AND make sure its a little smelly and turn yellow by two days from now, she could get even more suspicious and take me for a blood test. I'm in desperate need of help, so if anyone has some advice i'd be more than greatful! Thanks

 

Funny enough i go to college, however i still live with my parents and have been caught so many times smoking weed in the past as well, so they are really strict. This is the main reason i'm not living alone currently. However, i don't live near a walmart and have never seen AZO anywhere. Maybe something like asparagus could do the trick, but still the color won't be dark enough. Also my mom stands directly behind me so i can't have a bottle ready..
