Should I flush my ak47 and white dream#1 or keep feeding for couple more weeks?

Well your in soil, and flushing in soil is not recommended if you really dont have to- Tends to cause more issues than its worth. Your best bet in soil is to just stop all additional nutes and run plain water for the last 2-3 weeks and let the plant use up whats there and whats stored up. I grow outdoors in soil and my only concern ive ever had is i switched to plain water too soon- wishing I ran nutes a week or two longer as the buds ended up taking longer than expected... So I know it works as its obvious the plant is hungry a week or even two sooner than Id have liked it to be, and Im directly into the ground so not like I could flush even If I wanted to. Thats how I know just switching to water and allowing the plant to use up what is there works. its just getting the timing right thats the hard part-too soon and the plant goes hungry and starts to fade the leaves early, too late and there are still some low levels of nutes left in the soil and plant. 2 weeks is about the shortest time you want and 3 weeks seems to be the longest. The sweet spot is in there somewhere depending on strain and how much nutes are in the soil. If you fed alot its prob closer to 3 weeks, but if you were just feeding normal then aim closer to two weeks ok.
