Zero here does not follow the bro science rules anymore. I got a bowl loaded up with some CS sprayed buds, she was sprayed from like week 2 of the plants life for 11 days and i stopped, i'm sure me vaping the fresh mature buds now won't kill me or do anything but get me high! lol
I say test things, you won't die vaping some damn bud sprayed with some small ppm of a silver solution and your plant won't die the moment it goes past a certain number of days past being "Ready to chop" you decide when its ready
Try new things! Following a youtuber or the best grower here won't teach you the normal way of learning to grow and then you just are following someone elses recipe, make/find your own! its fun!!!
