Wait you guys actually waste your time ph'ing tap water lol I just throw tap water on my plants 7-14 days sometimes 5 cause the plant finished sooner then my feeding schedule, but really why do you guys pH? You phso that your plant can absorb nutrients and additives in my option you just want the plant to suck up the H2O!!!

I have definitely thought the same thing, but still pH my water for piece of mind, I guess. Lol. Hell, if I have been growing this plant for months, I figure why take the risk of not pHing the water! I also thought that it may stress the plant a bit, having a large pH swing (my tap water's pH is 8.2).

2 weeks before harvest date..first few days i like to give only ph water. after that flush till the run off is clear (my biobizz is brown)..and after again water when needed

Systemically, the plant, roots, buds and leave still have residual nutrients. I go further....only water the last 3 weeks, whether daily (depending on environmental factors, light, el sol) or every few days.

Absolutely loathe chemical exhale from plant/bud not 'detoxed' with supplements. Ugh!

Is it just me being stoned, or did nobody actually answer his question? "When to start flushing" ....lol :P
Well i'll do my best to answer it. The others have already told you for how long to flush. But when to actually start it, is down to knowing the strain you grow. And the first thing you need to accept, is that the listed flowering times will be 1-3 weeks too short. The listed times are doable if every single factor in your grow setup is perfect (and they rarely are for us small time growers). As an example, i am currently growing a kush listed as 7-8 weeks. Mine go 9 weeks
For a new grower, i would recommend the following as a base point, and then adjust as you learn more about the given strain and growing in general. Get that 60x scope (og better). When around 60-70% of the trics are cloudy, and the rest clear or semi clear, you can start your 2 week flushing.

I hope that helped a little

You should flush when you have 14 days left in flower. This means that the day before, when you have 15 days left you will need to give your girls a final feeding.

[mamboo]

Ph your tap water up to 14 days is suffice.

[corky1968]

Most people say 14 days.

I have done a few plants for 3 weeks before.

I guess the more nutrients you gave your plants the longer you should flush.
