Flushing.. Im thinking about starting to flush, as...

Hello ! 1st after reading your post I can tell you that : Bloombastic isn't organic at all (even with the green looking colour) and yes it increase the taste and smell like a beast (the trichomes production too if done at the proper moment). About the flush in soil the less you can do is about 7 days but the best you can do is 2 weeks (or more) , I would go with 10 days to be sure you get rid of the Bloombastic ( it's a powerful nutrient). I don't think it is too late as what I can see on your pics is a clear/milky trichomes ratio (more milky) and as it's a sativa you can harvest at different trichomes ratio for differents effects. If you start to flush now then in 10 days I supose that your trichome ratio will be around 90% milky so a good time to harvest a sativa. I hope it will help you 😁👍
