I'm about 3-4 weeks off on most, the jungle jim will probably need at least another 4-6 weeks and the purple power will probably take close to 6-7 more weeks. It could be longer though I've never grown any of these plants before. I don't see a point in flushing--I've tried both ways side by side with the same strain any didn't notice a difference in taste. Why starve your plant that you work so hard to grow for the most important final weeks of flowering? The buds get 20% of their weight in the last 2-3 weeks so in my mind that's the most important time to make sure they have the nutrients they need.
